Name two chemicals used to disinfect water.

The two chemicals used to disinfect water are chlorine and ozone.

[Extra information: Given below are the steps are involved in the purification of water:

1. All the physical impurities like stones, plastic bags, cans, etc. are removed by passing the water through bar screens.
2. The water is then taken to the grit and sand removal tank where impurities are removed by sedimentation.
3. Solid impurities and feces etc. are collected from the bottom of the water. These impurities collected are called sludge.
4. Clarified water is cleaned of other impurities by the aerator. All disease-causing bacteria are removed by chlorination.

When water undergoes clarification to remove suspended solids and solid particles, it is known as clarified water. The clarification of water is used in the pre-treatment of drinking water, prior to any further purification, and the treatment of wastewater and industrial effluents.]
