Suppose 1.00 g of NaOH is used to prepare 250 mL of an NaOH solution. Compare the expected molarity of this solution to the actual average molarity you measured in the standardization. What do you notice? Do you think the results would have been more accurate if a different type of acid or base were used in the standardization? Why, or why not? There are many different primary standards that could be used in a standardization titration. What are the...

Say for example, that you had prepared a Buffer C, in which you mixed 8.203 g of sodium acetate,NaC2H3O2, with 100.0 mL of 1.0 M acetic acid. 1A. What would be the initial pH of Buffer C 1B. If you add 5.0 mL of 0.5 M NaOH solution to 20.0 mL each of Buffer B( initial pH of Buffer B is 3.83), and Buffer C, Which buffer's pH would change less? Explain
