1.How does adding NaOH to deionized water affect the pH differently
than adding it to a buffer?
2. how would you find the Ka of solution 4, after it is
diluted from solution 3? the measured pH was 4.98 which gave a [H+]
concentration of 1.05x10^-5.
Part A - Determining the Acid Ionization Constant for Acetic Acid Solution 1 6. Take a 30.0 mL sample of 10 M HOAc and place it in a beaker. Using a pH meter, measure...
It's a weak acid strong base titration
Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
Epigenetics Video: Please go to the link for the video on D2L on epigenetics and then answer the questions: You may need to watch the video more than once to find the answers. Answer the following questions. Twins: 1. What is one reason why identical twins may not look or act the same? 2. Why would one twin having a disease make it more likely for the other twin to have the disease? 3. Why would they not always have...
This C++ Program consists of: operator overloading, as well as experience with managing dynamic memory allocation inside a class. Task One common limitation of programming languages is that the built-in types are limited to smaller finite ranges of storage. For instance, the built-in int type in C++ is 4 bytes in most systems today, allowing for about 4 billion different numbers. The regular int splits this range between positive and negative numbers, but even an unsigned int (assuming 4 bytes)...

Please read the article and answer about questions. You and the Law Business and law are inseparable. For B-Money, the two predictably merged when he was negotiat- ing a deal for his tracks. At other times, the merger is unpredictable, like when your business faces an unexpected auto accident, product recall, or government regulation change. In either type of situation, when business owners know the law, they can better protect themselves and sometimes even avoid the problems completely. This chapter...
Using the book, write another paragraph or two: write 170

Q: Compare the assumptions of physician-centered and
collaborative communication. How is the caregiver’s role different
in each model? How is the patient’s role different?
Answer: Physical-centered communication involves the specialists
taking control of the conversation. They decide on the topics of
discussion and when to end the process. The patient responds to the
issues raised by the caregiver and acts accordingly. On the other
hand, Collaborative communication involves a...
