Question

Match the acids in List 1 with their corresponding properties in List 2.

Answer 1

(A) : $H_{2}S{O}_5$ is hydrolysed to give $H_{2}S{O}_4$ and $H_2{O}_2$.

$O$ is in different oxidation state and peroxy linkage is present.

(B) : $H_{2}S{O}_4$ is hygroscopic in nature.

(C) : $H_2{S}_2{O}_7$ is hydrolysed to give $H_{2}S{O}_4$. It is hygroscopic in nature.

(D) : $H_2{S}_2{O}_3$ has $S=S$ bonds and $S$ is in different oxidation states (0 and +IV).

(E) : $H_2{S}_2{O}_8$ is hydrolysed to give $H_{2}S{O}_4$ and $H_2{O}_2$.$O$ is in different oxidation and peroxy linkage is present.
Note: In peroxy linkage, the oxidation number of oxygen is -1.
