Question

Identify the compound Y on the basis of the reactions given below. Also write the name and chemical formulae of A, B and C.

Answer 1

The compound ‘Y’ is sodium hydroxide. It forms A, B and C as follows :

`2"NaOH" + underset("(Y)")("Zn") -> "Na"_2"ZnO"_2 + underset("Sodium zincate (A)")("H_2(g)")`

`"NaOH" + underset("(Y)")("HCl") -> "NaCl" + underset("Sodium chloride(B)")("H"_2"O")`

`"NaOH" + underset(("Y"))("CH"_3"COOH") -> underset("Sodium acetate (Z)") ("CH"_3"COONa" + "H"_2"O")`
