Question

Define normality on the basis of 12th class???

Answer 1

Normality : it is defined as the number of grams equivalent of solute per litre of the solution .

Denoted by N

N = M *Molar mass /Equivalent mass

for acid

N = molarity * basicity

for base

N = Molarity * acidity

Answer 2

normality:---the number of gram equivalent of solute per litre solution is called normality.

it denoted by latter N

Normality = acidity *M

Normality = basecity *M

where M is called molarity .
