Question

Calculate pH and pOH of 0.02M HCl solution

Answer 1

Answer:

pH = 1.69897

pOH = 12.30103

Explanation:

At STP,

pH = -log(0.02M)

pH scale : 1-14

7 is the neutral.

below 7 pH is acid

and above 7 pH is Base

and pOH = 14 - pH

pH : - log ( total M of H+)

HCl ➡️ H+ ➕ Cl-

0.02M 0.02M 0.02M
