Question

what is normality ?and it's example and formula​

Answer 1

Answer:

Normality is a rarely used expression which indicates the concentration of a solution. It is defined as the gram equivalent weight per liter of solution. ... Here, a more favorable calculation for normality is considered, where the normality of a solution is equal to the molarity multiplied by the number of equivalents.

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

b. Calculate No. of Gram Equivalent of Solute

c. Calculate the volume in litre

d. Calculate the Normaility using the formula given above

Lets Calculate Normality of HCL using this

Suppose we have 36.5 gram of 1 L HCL solution.How can we calculate the Normality of HCL solution

a. Molecular Mass of HCL= 36.5

Number of H+ ion=1

So equivalent Weight = Molecular mass/1 = 36.5

b. No. of Gram Equivalent of Solute = Mass of Solute/Equivalent Weight = 36.5 /36.5 = 1

c. Volume here is given as 1 L

d. Normality will be calculated as

Normality = No. of Gram Equivalent of Solute/ Volume of Solution in L

=1 N

Answer 2

Normality is a rarely used expression which indicates the concentration of a solution. It is defined as the gram equivalent weight per liter of solution. ... Here, a more favorable calculation for normality is considered, where the normality of a solution is equal to the molarity multiplied by the number of equivalents.

Normality(N) = Molarity(M) x number of equivalents
