Question

What is the pOH of a 0.025 M [H+] solution? A.0.94 B.1.60 C.12.40 D.13.06

Answer 1

option C= 12.40

Step-by-step explanation:

Formula:

pH + pOH = 14

First of all we will calculate the pH.

pH = - log [H⁺]

pH = - log [0.025]

pH = - (-1.6)

pH = 1.6

Now we will put the values in formula,

pH + pOH = 14

pOH = 14-pH

pOH = 14 -1.6

pOH = 12.4

The pOH of solution is 12.4.
