Vedclass · Answer

(B) strong electrolyte is a substance that completely dissociates into its constituent ions in an aqueous solution.$NH_4OH$ is a weak base.$HCN$ is a weak acid.$H_2SO_3$ is a weak acid.$Ca(NO_3)_2$ is a salt of a strong acid $(HNO_3)$ and a strong base $(Ca(OH)_2)$,which dissociates completely in water as $Ca(NO_3)_2(aq) \rightarrow Ca^{2+}(aq) + 2NO_3^-(aq)$.Therefore,$Ca(NO_3)_2$ is a strong electrolyte.
