During a titration experiment, a 150.0 mL solution of 0.05 M sulfuric acid (H2SO4) is neutralized by 300.0 mL solution with an unknown concentration of sodium hydroxide (NaOH).

Question

What is the concentration of the sodium hydroxide solution?

Answer 1

M1=0.05M
M2=?
V1=150 mL
V2=300mL
So,
M1V1=M2V2
(0.05)(150)=(300)M2
M2(300)=7.5
M2=7.5/300
M2=0.025M
