Question

what is normalityof a solution?​

Answer 1

HEY MATE YOUR ANSWER =》♤♡♡♡♡

• DEFINATION;

Normality is defined as the number of gram equivalent present in per litre solution. It is used for acid or base solution

$n = \frac{gram \: eq. \: of \: solute}{volume \: of \: solution \: in \: litre}$

• SOME POINT ABOUT NORMALITY

1. Normality unit is N or eq/L .It depends on the chemical reaction being studied and depends on temperature too. So ,it is meaning with respect to the chemical reaction
2. It is the reactive capacity of the solution and it is called equivalent concentration
3. This is used in acid-base reactions and redox reactions

HOW TO CALCULATE NORMALITY OF SOLUTION=》

a. Find the equivalent weight of the solute based on the chemical reaction it is going to be used

a. Find the equivalent weight of the solute based on the chemical reaction it is going to be usedb. Calculate No. of Gram Equivalent of Solute

a. Find the equivalent weight of the solute based on the chemical reaction it is going to be usedb. Calculate No. of Gram Equivalent of Solutec. Calculate the volume in litre

a. Find the equivalent weight of the solute based on the chemical reaction it is going to be usedb. Calculate No. of Gram Equivalent of Solutec. Calculate the volume in litred. Calculate the Normality using the formula given above
