A white sodium salt dissolves readily in water to give a solution which is neutral to litmus. When silver nitrate solution is added to the aforementioned solution, a white precipitate is obtained which does not dissolve in dil. nitric acid. The anion is :

Options

A $\mathrm{CO}_3^{2-}$
B $\mathrm{SO}_4^{2-}$
C $\mathrm{S}^{2-}$
D $\mathrm{Cl}^{-}$

Correct answer

D. $\mathrm{Cl}^{-}$

Step-by-step solution

Therefore, the required locus is

\frac{3}{x}+\frac{2}{y}+\frac{1}{z}=1
