Question

Define normality equation

Answer 1

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. The reasonnormality is rarely used lies in the definition of gram equivalent weight................

Answer 2

$\huge\textbf{Normality :}$


Normality can be defined as the number of grams equivalents present in 1 litre of solution.


$Normality$ = $\frac{Number\:of\:gram\:Equivalent}{Volume\:of\:solution}$


$Number\:of\:grams\: equivalent$ = $\frac{Given\:mass}{Equivalent\:mass}$

= $\frac{w}{equivalent\:weight}$

$Equivalent\:weight$ = $\frac{Molar\:mass}{Valency}$

= $\frac{m}{valency}$

$N$ = $Valency$ × $\frac{w}{m}$ × $\frac{1000}{volume}$

$\textbf{N}$ = ${Valency\:×\:M}$
