Question

when chlorine and sodium hydroxide being produced during electrolysis of brine are allowed to mix, a new chemical is formed.name the chemical and write its uses

Answer 1

Brine is a solution of sodium chloride (NaCl) and water (H₂O). When sodium hydroxide and chlorine are allowed to mix, the reaction goes as below:
$C{l}_2\left(aq\right)+2O{H}^{-}\left(aq\right)\leftrightarrow OC{l}^{-}\left(aq\right)+C{l}^{-}\left(aq\right)+H_{2}O\left(l\right)$
Sodium hyprochlorite is produced from the above reaction.
Uses of sodium hypochlorite:

• It is an active ingredient in bleaching powder.
• It is used as disinfectant.
• It is used in cleaning water.
