Question

what is normality in chemistry

Answer 1

In chemistry,

•Normality is also known as the equivalent concentration of a solution.

•Normality is a measure of concentration equal to the gram equivalent weight per liter of solution.

Answer 2

$\underline{\underline{\huge{\mathfrak{A{\textbf{\red{nswer :}}}}}}}$


$\huge\textbf{Normality :}$

Defined as number of moles of gram equivalents present in 1 lit. of solution...

It is denoted by N..

N = $\dfrac{Number\:of\:gram\: Equivalent}{Volume\:of\:Solution\:(in\:lit.}$

Number of gram equivalent =

$\dfrac{Given\:Mass}{Equivalent\:Mass}$

=> $\dfrac{w}{eq.\:wt.}$

Equivalent weight =

$\dfrac{Molecular\:Mass}{Valdncy\:or\:Acidity\:or\:Bascity}$

=> $\dfrac{m}{Valency}$

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


N = Valency × M (molarity)
