Nitration mixture contains equimolar ratio (i.e. $1: 1)$ of nitric acid and sulphuric acid.
It contains $\underset{+}{N}O _{2}, HSO _{4}^{-}$ and $H _{2} O$ species.
It does not contain $SO _{4}^{2-}$ ions.
This can be explained on the basis of generation of nitronium
$\overset{+}{N}O _{2}$ ion from nitrating mixture.
Generation of $\overset{+}{N}O _{2}$ ion
Step 1
Step II $H - \overset{\underset{|}{H}}{O^+} - NO_2 {<=>} \overset{+}{N}O_2 + H_2O$
Group 15 elements are also known as nitrogen group elements or nitrogen family.
It consists of:
Nitrogen (N)
Phosphorus (P)
Arsenic (As)
Antimony (Sb)
Bismuth (Bi)
Moscovium (Mc)
They are present on the right side of the periodic table. All the elements are arranged based on their atomic weight. The elements with similar properties reside in a column called the group.
All Group 15 elements have the electron configuration ns2np3 in their outer shell, where n is the principal quantum number.
