Question

100ml of 0.01N HCL is mixed with 200ml of 0.02 HCL .normality of resultant solution is

Answer 1

N₁ = 0.01 N.

V₁ = 100 mL.

N₂ = 0.02 N

V₂ = 200 mL.

V = V₁ + V₂ = 100 + 200 = 300 mL.

Using Normality Equation,

NV = N₁V₁ + N₂V₂

∴ N × 300 = 0.01 × 100 + 0.02 × 200

⇒ 300 × N = 1 + 4

∴ N = 5/300

⇒ N = 0.0167 N.

Hence, the Normality of the Final Solution is 0.0167 N.

Hope it helps.
