· Sodium hydroxide: Through the electrolytic process, sodium chloride can be broken down to produce sodium hydroxide (NaOH) and chlorine gas.
· Bleaching powder: Bleaching powder, also known as calcium hypochlorite (CaOCl2), is manufactured using slaked lime (Ca(OH)2) and chlorine gas (Cl2), which can be obtained from sodium chloride (NaCl) through electrolysis.
Therefore, common salt can be used as a starting material for all the options listed.
