Question

what will be the change in the concentration of Ions when :
a. hydro chloric acid is diluted
b. potassium Hydroxide is diluted

Answer 1

a. h^+ and cl^-
b.h^+ and oh^-

Answer 2

Answer:

when HCL is diluted then concentration of hydronium ions decreases.

when potassium hydroxide is diluted then  hydroxyl ions decreases.

Explanation:

When an acidic solution is diluted with water the concentration of H + ions decreases and the pH of the solution increases towards 7.

Similarly, when an alkali is diluted with water the concentration of OH - ions decreases.

Hope you get your answer!
