Question

100ml of decinormal hcl is mixed with 100ml of seminormal h2so4 calculate normality

Answer 1

M1 = 1/10

V1 = 100ml = 0.1L

n factor of HCl = 1

N1 = M1 x n factor = 1/10 x 1 = 1/10

M2 = 1/2

V2 = 100ml = 0.1L

n factor = 2

N2 = M2 x n factor = 1/2 x 2 = 1

N1 X V1 + N2 X V2 = N3 X V1 + V2

1/10 x 0.1 + 1 x 0.1 = N3 X 0.2

0.01 + 0.1 = N3 X 0.2

N3 = 0.11/0.2 = 0.55
