Question

240(b). What happens when Chlorine is passed through slaked lime?

Answer 1

• Slaked lime is also known as Calcium hydroxide and its chemical formula is Ca(OH)₂.
• When Chlorine is passed through slaked lime, it will form Calcium oxychloride.
• Calcium oxychloride is also known as bleaching powder and its chemical formula is CaOCl₂.
• The chemical equation for the reaction is as follows:

$\underset{\mathrm{Slaked}\mathrm{lime}}{\mathrm{Ca}{\left(\mathrm{OH}\right)}_2}+\underset{\mathrm{Chlorine}}{\mathrm{C}{\mathrm{l}}_2}\to \underset{\mathrm{Bleaching}\mathrm{powder}}{{\mathrm{CaOCl}}_2}+\underset{\mathrm{Water}}{{\mathrm{H}}_2\mathrm{O}}$
