Correct Answer

Explanation

The impurities formed during the laboratory preparation of chlorine gas are typically removed by passing the gas through a solution of sodium hydroxide (NaOH) or calcium hydroxide (Ca(OH)?). This process helps to neutralize any acidic impurities such as hydrogen chloride (HCl) or sulfur dioxide (SO?) that may be present. So, the correct option would be HCl.
