The molarity of the HNO₃ solution : 0.212 M

Further explanation

Given

62.4 mL HNO₃

56.25 mL of a 0.235 M KOH

Required

Molarity HNO₃

Solution

Titration formula

M₁V₁n₁=M₂V₂n₂

1= HNO₃, 2 = KOH

n = acid base valence (amount of H⁺/OH⁻ released,for HNO₃ and KOH = 1)

Input the value :

M₁ x 62.4 x 1 = 0.235 x 56.25 x 1


\tt M_1=(0.235* 56.25* 1)/(62.4* 1)\\\\M_1=0.212
