Homework Answers
pH = 3.4
Explanation
The pKa value rounded to nearest whole number is 6.0
pKa = 6.0
Ka = 10-pKa
Ka = 10-6.0
Ka = 1.0 x 10-6
initial concentration of acid = 0.150 M
| ICE table | HA (aq) |  |
H+ (aq) | A- (aq) |
| Initial conc. | 0.150 M | 0 | 0 | |
| Change | -x | +x | +x | |
| Equilibrium conc. | 0.150 M - x | +x | +x |
Ka = [H+]eq[A-]eq / [HA]eq
1.0 x 10-6 = [(x) * (x)] / (0.150 M - x)
Solving for x, x = 3.87 x 10-4 M
pH = -log[H+]
pH = -log(3.87 x 10-4 M)
pH = 3.41
