Question

Volume of HCl V1 = 20 ml

Strength of HCl N1 = ?

Volume of NaOH V2 (obtained from graph) = …………. ml

Strength of NaOH N2 = 0.2 N

According to the law of volumetric analysis,

V1N1=V2N2

N1 = V2N2 / V1



Strength of HCl = …….. N

Calculation of amount of HCl

The amount of HCl present in 1000 ml of the given solution=Equivalent weight x strength



= 36.46 x ………



= …… g​
