Problem
ProblemHI is a strong acid (Ka = 3.2 × 109). Calculate [H+], [OH−], pH and pOH of a 7.1 × 10−2 M HI solution.
A
[H+] = 7.1 × 10−2 M
[OH−] = 1.4 × 10−13 M
pH = 1.15
pOH = 12.85
[OH−] = 1.4 × 10−13 M
pH = 1.15
pOH = 12.85
B
[H+] = 7.1 × 10−2 M
[OH−] = 1.4 × 10−13 M
pH = 8.50
pOH = 5.50
[OH−] = 1.4 × 10−13 M
pH = 8.50
pOH = 5.50
C
[H+] = 7.1 × 10−2 M
[OH−] = 7.1 × 10−16 M
pH = 1.15
pOH = 15.15
[OH−] = 7.1 × 10−16 M
pH = 1.15
pOH = 15.15
D
[H+] = 7.1 × 10−2 M
[OH−] = 7.1 × 10−12 M
pH = 1.15
pOH = 11.15
[OH−] = 7.1 × 10−12 M
pH = 1.15
pOH = 11.15
