Question

I find the pH of a solution whose hydrogen ion concentration 10^-3mol/l also deduce the pOH of the solution

II​

Answer 1

pOH = 11

pH = 3

Step-by-step explanation:

Given data:

Hydrogen ion concentration = 10⁻³ mol/L

pOH of solution = ?

pH of solution = ?

Solution:

pH = -log[H⁺]

Now we will put the values.

pH = -log[ 10⁻³]

pH = -(-3) log 10

pH = 3

pOH of solution:

pOH + pH = 14

pOH = 14 - pH

pOH = 14 - 3

pOH = 11
