Question

What is the [ OH -1 ] in a 0.01 M KOH solution? a. 1 X 10^-2 M b. 1 X 10^-14M c. 1 X 10^-7Md. 1X10^-12M

Answer 1

Step-by-step explanation

Given:

[KOH] = 0.01 M

What to find:

The hydroxyl concentration, [OH⁻¹].

Step-by-step solution:

pH or pOH is the measure of acidity or alkalinity of a solution.

Acids have pH ranging from 1 to 6.9 and bases have pH ranging from 7.1 to 14. Neutral substances have a pH of 7.

The dissociation of KOH in aqueous medium is:T
