A)
Given:
[OH-] = 9.9*10^-7 M
use:
pOH = -log [OH-]
= -log (9.9*10^-7)
= 6.00
use:
PH = 14 - pOH
= 14 - 6.00
= 8.00
Answer: 8.00
B)
Given:
[OH-] = 3.6*10^-8 M
use:
pOH = -log [OH-]
= -log (3.6*10^-8)
= 7.4437
use:
PH = 14 - pOH
= 14 - 7.4437
= 6.5563
Answer: 6.56
C)
Given:
[OH-] = 7.2*10^-11 M
use:
pOH = -log [OH-]
= -log (7.2*10^-11)
= 10.1427
use:
PH = 14 - pOH
= 14 - 10.1427
= 3.8573
Answer: 3.86
D)
Given:
[OH-] = 9.5*10^-2 M
use:
pOH = -log [OH-]
= -log (9.5*10^-2)
= 1.0223
use:
PH = 14 - pOH
= 14 - 1.0223
= 12.9777
Answer: 12.98
