Question

pOH of a solution is 5.2. What is its pH. Comment on the nature (acidic, basic
or neutral) of this solution

Answer 1

Answer:

pH = 5.2 , Solution is acidic

Explanation:

pH = 7  is Neutral

pH < 7 is Acidic as number keep reducing acidity keep increasing

pH > 7 is Basic and basicity will keep increasing with increase in number

now pH given is 5.2

5.2 < 7

=> Solution is acidic

The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity of the solution.

pH = 5.2 , Solution is acidic

Answer 2

Answer:

pH = 8.8. Solution is weakly basic

Explanation:

We know that,

pH + pOH = 14

Given, pOH = 5.2

∴ pH + 5.2 = 14

  pH = 14 - 5.2

  pH = 8.8

As we know that solutions having pH value between 7 to 10 are weakly basic, thus this solution whose pH is 8.8 (8.8 is between 7 to 10) is also a weakly basic solution.
