Q. The number of $P — OH$ bonds and the oxidation state of phosphorus atom in pyrophosphoric acid $(H_4P_2O_7)$ respectively are

AIIMSAIIMS 1995The p-Block Elements - Part2

Solution:

Pyrophosphoric acid : $H _{4} P _{2} O _{7}$

Let Oxidation state of $P$ be $x$

$\Rightarrow 4 \times(+1)+2 x+7 \times(-2)=0$

$\Rightarrow 4+2 x-14=0 $

$\Rightarrow x=+5$

basicity of acid is four.
