Question 1

You dissolve 1.25 grams of an unknown diprotic acid in 200.0 mL of H2O. This solution is just neutralized by 5.00 mL of a 1.00 M NaOH solution. What is the molar mass of the unknown acid?

◦ 250
◦ 125
◦ 31.3
◦ 500
◦ None of these are correct.

Question 2

You have 100.0 mL of 0.100 M aqueous solutions of each of the following acids: HCN, HF, HCl, and HC2H3O2. You titrate each with 0.100 M NaOH (aq). Rank the pHs of each of the solutions when each are titrated to the equivalence point, from highest to lowest pH.
 
Ka for HCN = 6.2 × 10–10
 
Ka for HF = 7.2 × 10–4
 
Ka for HC2H3O2 = 1.8 × 10–5
 

​


◦ HCN, HC2H3O2, HF, HCl
◦ HCl, HF, HCN, HC2H3O2
◦ HF, HCN, HC2H3O2, HCl
◦ HC2H3O2, HCl, HCN, HF
◦ None of these are correct.
