Acids and Bases Assignment
You have made it to Dr. Muchmerry’s lab hoping to discuss how the conference went, but she is not there. You’ve once again found a note on the lab bench with a request.
Good Afternoon,
Thank you for your work helping me to prepare for the conference, it went great. Since I have been back, I have been working on a post for the school’s Facebook page. Herzing has asked us to share an interesting piece of information that relates to chemistry. So, I’ve decided to write a post about acids and bases.
– Dr. Ima

This week in your chemistry class, you have been introduced to the process of titration. Remember that titration is the process used to determine the unknown concentration of a solution by using the known concentration of another solution. This process uses a buret to measure the volume of titrant that is added to the analyte. Below is a set of measurements that I would like you to solve:
How to read a buret:
Suppose you titrated a sample of NaOH with 0.150 M of HCl. Your starting volume on the burette is 0.00 mL. This is your final reading. How much NaOH was dispensed from the buret?
Answer:
Suppose you titrated a sample of NaOH with 0.150 M of HCl. Your starting volume on the burette is 0.00 mL. This is your final reading. How much NaOH was dispensed from the buret?
Answer:
Well done!
Now we need to solve for an unknown.
For your review, I have included a link to a video for you to review titration and how to solve for an unknown. https://www.youtube.com/watch?v=d1XTOsnNlgg
Using the information I’ve provided, calculate the molarity of the HCl concentration using the information provided.
Here’s the reaction:
HCl + NaOH —-> H2O + NaCl
Volume of HCl: 20.0 mL
Concentration of HCl: UNKNOWN
Know concentration of NaOH: 0.100 M
Titrate end point or total of NaOH volume dispensed: 48.6mL
Answer:
From the above information, would you put the HCl solution in the buret or in the Erlenmeyer flask in this titration reaction?
Answer:
Would you add the indicator, in this case we would use Phenolphthalein, to the HCl or NaOH?
Answer:
Calculate the molarity of the HCl concentration using the information provided.
Here is the reaction:
HCl + NaOH —-> H2O + NaCl
Volume of HCl: 10.0 mL
Concentration of HCl: UNKNOWN
Concentration of NaOH: 0.100 M
Volume of NaOH dispensed to reach endpoint 12.00 mL
Answer:
If you walk into any kitchen, bathroom, laundry room or pantry, you are bound to find numerous types of acids and bases.
Using the information provided in the chart below, completely fill in the missing pieces of information.

Using two outside sources, cited according to APA format, create a (pretend) social media post that addresses how two of the above acids or bases impact the body. Remember, your post needs to be at least 500 words and discuss how an acid and/or a bases impacts the body. For example, you could discuss the role carbonic acid has on your tooth enamel or the role of aluminum hydroxide has on the stomach.
I look forward to reading your post.

You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.
Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.
Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.
The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.
ADDITIONAL INSTRUCTIONS FOR THE CLASS
Discussion Questions (DQ)
Initial responses to the DQ should address all components of the questions asked, include a minimum of one scholarly source, and be at least 250 words.
Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source.
One or two sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words.
I encourage you to incorporate the readings from the week (as applicable) into your responses.
Weekly Participation
Your initial responses to the mandatory DQ do not count toward participation and are graded separately.
In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies.
Participation posts do not require a scholarly source/citation (unless you cite someone else’s work).
Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week.
APA Format and Writing Quality
Familiarize yourself with APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required).
Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation.
I highly recommend using the APA Publication Manual, 6th edition.
Use of Direct Quotes
I discourage overutilization of direct quotes in DQs and assignments at the Masters’ level and deduct points accordingly.
As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content.
It is best to paraphrase content and cite your source.
LopesWrite Policy
For assignments that need to be submitted to LopesWrite, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me.
Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes.
Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own?
Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for tips on improving your paper and SI score.
Late Policy
The university’s policy on late assignments is 10% penalty PER DAY LATE. This also applies to late DQ replies.
Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances.
If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect.
I do not accept assignments that are two or more weeks late unless we have worked out an extension.
As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading.
Communication
Communication is so very important. There are multiple ways to communicate with me:
Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class.
Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours.
