Determining the Molarity of Nitric Acid Solution

What is the molarity of the nitric acid?

A 45.0 ml sample of nitric acid is neutralized by 119.4 ml of 0.2 M NaOH.

Answer

The molarity of the nitric acid is 0.53 M.

The process of determining the molarity of a nitric acid solution involves utilizing the dilution formula. The dilution formula is given as:

C1V1 = C2V2

Where:

C1 = initial concentration of the acid

V1 = initial volume of the acid

C2 = final concentration of the acid

V2 = final volume of the acid

Given the parameters:

V1 = 45 mL

C2 = 0.2 M

V2 = 119.4 mL

Substitute the given parameters into the dilution formula:

C1 = (C2V2) / V1

C1 = (0.2 x 119.4) / 45

C1 = 23.88 / 45

C1 = 0.53 M

Hence, the molarity of the nitric acid solution is 0.53 M.
