Question

What is the pOH of a 0.025 M [H+] solution?

Answer 1

POH=14-pH

pH=-lg[H⁺]

pOH = 14 + lg0.025 = 12.4

Answer 2

Answer: 12.4

Explanation: pH or pOH is the measure of acidity or alkalinity of a solution.

Acids have pH ranging from 1 to 6.9 and bases have pH ranging from 7.1 to 14.Neutral substances have pH of 7.

First we have to calculate the pH.

$pH=-\log [H^+]$

$pH=-\log (0.025)$

$pH=1.60$

Now we have to calculate the pOH.

$pH+pOH=14\\\\pOH=14-pH\\\\pH=14-1.60=12.4$

Thus pOH of the solution is 12.4
