Tips:

  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

weak, strong
 
weak, weak
 
strong, weak
A weak acid HA has a pKa = 3.50. At what pH will the concentration of HA be 100 times larger than the concentration of A- in this solution?
1.50
A weak acid HA has a pKa = 4.00. At what pH will the concentration of HA be ten times larger than the concentration of A- in this solution?
3.0
Use the equilibria below for the triprotic acid for this question. (The ↔ represents the equilibrium double arrow.) H3A ↔ H+ + H2A- pKa1 = 2.00 H2A- ↔ H+ + HA2- pKa2 = 6.00 HA2- ↔ H+ + A3-
