[NaOH]= 0.113M

Question

V of NaOH needed to titrate = 0.0037L
V of unknown weak organic acid = 0.025L

Find:
The initial concentration of this weak acid.

Answer 1

If it's a monoprotic weak acid, then
L acid x M acid = L NaOH x M NaOH

Answer 2

Ok How do I find the initial concentration of the acid?

Answer 3

Substitute the numbers from the problem and solve for M acid.
