Question

It takes 12. 5 ml of a 0. 30 m hcl solution to neutralize 285 ml of naoh solution. What is the concentration of the naoh solution?

Answer 1

Answer: M₂ = 0

Explanation:

HCl + NaOH — NaCl + H2O

For acid base titrations:

M₁ V₁ = M₂ V₂

where lower-script 1 and 2 are the molarity and volume for acid and base respectively.

M₁ = 0.30 M

V₁ = 12.5 ml

M₂ = (unknown)

V₂ = 285

0.30 x 12.5 = 285 M₂

M₂ = 3.8/ 285

M₂ = 0

p.s I think there is an error with the typed question. It’s not possible to use 285 ml of base against 12.5 ml of acid.
