Question

What is Normality (in chemistry)​

Answer 1

As per the standard definition, normality is described as the number of gram or mole equivalents of solute present in one litre of a solution.

Answer 2

▪Normality :-

It is the gram equivalent weight of solute dissolved in 1 litre of solution.

⟼ It is denoted by N .

$\purple{ \large \underline {\boxed{{\bf  N = \frac{W_{2}}{E _{2} \times V _{solution}(in \: L) \: } } }}} \\ \bf where \: \: 2 \: \: represents \: \: solute$

• E = Equivalent Weight

• W = Given weight

▪Related Formulas :-

1 》 Formula for Equivalent Weight :

$\red{\bf E _{2} = \dfrac{molecular \: \: wt.}{n _f} }$

$\sf n_f$ = n - factor

2 》Formula for gram equivalent weight:

$\red {\bf gr. \: eq. \: wt. = \dfrac{W _{2}}{E _{2}} }$

☆ n - Factor :-

• For Acids = No. of $\sf H^+$ ions.
• For Bases = No. of $\sf OH^-$ ions.
• For Salts = Charge or Valancy.
