Question

How to calculate normality, molarity? Please explain step by step in examples?

Answer 1

The equation of normality that helps to estimate the volume of a solution required to prepare a solution of different normality is given by,

Initial Normality (N1) × Initial Volume (V1) = Normality of the Final Solution (N2) × Final Volume (V2)

Suppose four different solutions with the same solute of normality and volume are mixed; therefore, the resultant normality is given by;

NR = [NaVa + NbVb + NcVc + NdVd] × [Va+Vb+Vc+Vd]-1

If four solutions having different solute of molarity, volume and H+ ions (na, nb, nc, nd) are mixed then the resultant normality is given by;

NR = [naMaVa + nbMbVb + ncMcVc + ndMdVd] × [Va+Vb+Vc+Vd]-1.
