Question

Chlorine reacts with cold and dilute \[\ce{NaOH}\] to give:

Options

• NaCl and NaClO₃

• NaCl and NaClO

• NaCl and NaClO₄

• NaClO and NaClO₃

Answer 1

NaCl and NaClO

Explanation:

When a cold and dilute sodium hydroxide solution reacts with chlorine, sodium chloride and sodium hypochloride are obtained. The reaction is as follows:

\[\ce{2NaOH + Cl2 -> NaCl + NaOCl + H2O}\]

Hence, the salts formed are NaCl and NaClO.
