Question

A 40 ml solution of sodium hydroxide (NaOH) with concentration 0.25 M was titrated with a

sample of 50 ml solution of hydrochloric acid (HCI). What is the concentration of the HCI
solution?

Answer 1

C1V1/C2V2=n1/n2
40*0.25/50*x=1/1
40*0.25*1=50*x*1
10=50x
x=0.2
The conc. Of the HCl solution is 0.2M
