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 aformentioned solution, a white precipitate is obtained which does not dissolve in dil. nitric acid. The anion is :
Show Hint
- \(\mathrm{CO_3^{2-}}\)
- \(\mathrm{SO_4^{2-}}\)
- \(\mathrm{Cl^-}\)
- \(\mathrm{S^{2-}}\)
The Correct Option is C
Solution and Explanation
\(\mathrm{Ag_2CO_3}\) would dissolve in dil. \(\mathrm{HNO_3}\), and \(\mathrm{Ag_2S}\) is black.
\(\mathrm{Ag_2SO_4}\) is fairly soluble, so no insoluble white precipitate is expected in dilute solution.
\(\mathrm{Cl^- + Ag^+ \rightarrow AgCl\downarrow}\) is white and insoluble in dil. \(\mathrm{HNO_3}\).
Answer: (3) \(\mathrm{Cl^-}\)

- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
