Identify the compound (A) which is a universal solvent. Compound A reacts with chlorine gas to give B and C. Compound A dissolves in an ionic compound of silicon to give compound D. Identify A and write the equations involved in the formation of B, C and D.

Explanation

(i) The universal solven is water (A).
Water reacs with chlorine gas to form hydrochloric acid (B) and hypo chlorous acid (C ).
`C_2+underset((A))H_2Otounderset((B))HCl+underset((C ))HOCl`
(iii) Water reacts with silicon tetra chloride `(SiCl_4)` to give silicon dioxide (D).
`SiCl_4+underset((A))2H_2Otounderset((D))SiO_2+underset((B))4HCl`
