Electrolysis
and useful products
 

Chlorine is widely used in the chemical industry and its uses range from a strong bleaching agent to the formation of plastics such as polyvinyl chloride.

Sodium hydroxide, or caustic soda as it is often called, is used in paint strippers, toilet cleaners and oven cleaners.

The formation of chlorine and sodium hydroxide occurs simultaneously in an electrolytic cell called a membrane cell.

Sodium hydroxide is the active ingredient of Drano and this brand of oven cleaner.

Calculate the molarity of the sodium hydroxide solution from the information on the can.
