Problem 1.1:
What is the pH of a solution of 0.36 M HCl, 0.62 M NaOH, and 0.15 M
HNO3?
Problem 1.2:
What percent of formic acid (HCOOH) is dissociated in a 0.1 M solution of
formic acid? The
Ka of formic acid is 1.77 x 10-4.
Problem 1.3:
What happens to the pH of a 0.1 M solution of formic acid when enough HCl
(g) is added to make
the solution 0.01 M in HCl?
Problem 1.4:
What is the pH of a 0.001 M solution of H2SO4?
HSO4- has a pKa of 1.2 x 10-
2.
