Answer 2

Answer: Ratio of  $x: y$ is $2:1$

Explanation:

• Ionisable H atoms are the  acidic hydrogens which are Ionisable as $H^{+}$ ions.

• In Oxoacids of phosphorus,  $P-H$ bonds cannot be ionized to produce $H^{+}$ ions but the $H$ atoms that are bound to oxygen in $P-OH$ form can be ionized.

• In $H_{3}PO_{3}$ there are two $-OH$ groups that can which can give $2$ ionisable  or acidic hydrogens. Therefore value of x is $2$.

• And in $H_{3} PO_{2}$ there is one $-OH$ group that can which can give $1$ ionisable  or acidic hydrogen. Therefore value of y is $1$.

        So ratio of $x:y$ is $2:1$.
