Question

What is the reaction of chlorine with cold dilute NaOH solution?

Option 1: Formation of sodium chloride and water.
Option 2: Formation of sodium hypochlorite and hydrogen gas.
Option 3: Formation of sodium chlorate and oxygen gas.
Option 4: Formation of sodium chloride and chlorine gas.

Answer 1

When chlorine reacts with cold dilute NaOH, it produces sodium chloride and sodium hypochlorite, along with water as a byproduct.

Step-by-step explanation:

The reaction between chlorine and cold dilute NaOH solution does not produce a single product but rather a mixture of sodium chloride (NaCl) and sodium hypochlorite (NaClO). This can be represented by the chemical equation:

Cl2 + 2NaOH → NaCl + NaClO + H2O

From the given options, the correct answer is Option 2: Formation of sodium hypochlorite and water. It is important to note that hydrogen gas is not produced in this reaction. Instead, water is formed along with the sodium compounds.
