Calculate the H+ and OH- concentration of a 4.3 x 10-3M solution of NaOH.

Question

1. Calculate the H+ and OH- concentration of a 4.3 x 10-3M solution of NaOH.

Answer 1

! mole of NaOH has 1 mole of OH^- ions. Therefore the concentration of NaOH and OH^- are equal. Therefore

[OH^-] = 4.3 * 10^-3 M

Recall,

[OH^-] * [H⁺] = 10^-14

[H⁺] = 2.33* 10^-12
