Question

Calcula el pH de las siguientes concentraciones:
[H+]= 2.64 x 10 -7
[H+]= 5.47 x 10 -2
[OH-]= 9.82 x 10 -3
[OH-]= 1.87 x 10 -14

Answer 1

Respuesta:

1. pH = - log 2.64 × 10 ^-7 = 6.58

2. pH = -log 5.47 × 10 ^-2 = 1.26

3. pOH = -log 9.82 ×10 ^ -3 = 2.0

pH = 14 - 2.0 = 12

4. pOH = - log 1.87 × 10 ^-14 = 13.7

pH = 14 - 13.7 = 0.3
