Consider the following salts, which one(s) when dissolved in water will produce a basic solution?

\begin{array}{cccccccccccccccccccc} {{\text{I}}{\text{.}}\,\,\,RbCl{O_4}}&{{\text{II}}{\text{.}}\,\,\,NaN{O_2}}&{{\text{III}}{\text{.}}\,\,\,N{H_4}Cl}&{{\text{IV}}{\text{.}}\,\,\,NaCl} \end{array}

View answer and explanation

Correct option: B

Only II

Option B (Only II) is correct because

NaN{O_2}

is a salt of a weak acid (

HN{O_2}

) and a strong base (NaOH), which hydrolyzes in water to produce a basic solution.
