Question

A 25.00 mL sample of a hydrochloric acid solution was titrated to completion with 34.55 mL of 0.1020 M sodium hydroxide. What was the concentration of the hydrochloric acid

Answer 1

The concentration of hydrochloric acid with a volume of 25mL titrated with 34.55 mL of 0.1020 M sodium hydroxide is 0.141M.

How to calculate concentration?

The concentration of an acid in a titration procedure can be calculated using the following expression:

CaVa = CbVb

Where;

• Ca = concentration of acid
• Cb = concentration of base
• Va = volume of acid
• Vb = volume of base

• Ca = ?
• Cb = 0.102M
• Va = 25mL
• Vb = 34.55mL

Ca × 25 = 0.102 × 34.55

25Ca = 3.52

Ca = 0.141M

Therefore, the concentration of hydrochloric acid with a volume of 25mL titrated with 34.55 mL of 0.1020 M sodium hydroxide is 0.141M.
