Question

With excess of water, both $P_{2}O_{5}$ and $PCl_{5}$ give

$H_{3}PO_3$

$H_{3}PO_{2}$

$H_{3}PO_{4}$

$H_4P_2O_7$

Answer

$H_{3}PO_{4}$

Explanation

Solution

Both $P _{2} O _{5}$ and $PCl _{5}$ give $H _{3} PO _{4}$ With excess of water.
$P _{2} O _{5}+3 H _{2} O \longrightarrow 2 H _{3} PO _{4}$
$PCl _{5}+4 H _{2} O \longrightarrow H _{3} PO _{4}+5 HCl$
