Answer: calcium hydroxide (slaked lime)
Explanation:
Chlorine gas reacts with _______ to form bleaching powder.
When calcium hydroxide (slaked lime) reacts with chlorine, it gives calcium oxychloride (bleaching powder) and water is formed. Aqueous solution of bleaching powder is basic in nature.
Calcium hydroxide is also known as slaked lime. When chlorine gas is passed over the dry slaked lime thus bleaching powder and water is produced.
Calcium hypochlorite is a compound with formula Ca(ClO)2 .
Calcium hypochlorite is produced industrially by treating lime(Ca(OH) 2
with chlorine gas.
The reaction is as follows:-
2Cl2 +2Ca(OH)2 →Ca(OCl)2 +CaCl2 +2H2O
