Question

It takes 12.5mL of a 0.30M HCl solution to neutralize 285mL of NaOH solution.

What is the concentration of the NaOH solution?

Answer 1

Molarity NaOH = 0.0263M

Step-by-step explanation:

Molarity Acid x Volume Acid = Molarity Base x Volume Base

12.5ml x 0.60M = 285ml x M(base)

M(base) = 12.5ml x 0.60M / 285ml = 0.0263M
