why is caustic soda added to drinking water before it is pumped to homes and factories​

Answers

Answer 1

The reason why caustic soda is added to drinking water before it is pumped to homes and factories ​is help to decreases the solubility of dangerous metals, like lead and copper.

What is the usefulness of  addition of caustic soda to drinking water before pumping to homes?

Dangerous metals like lead and copper become less soluble in caustic soda. These metals are heavy and bulky in their insoluble state, which increases the possibility that they may get stuck in a filter system or sink to the bottom of a tank where they can be collected.

A typical chemical used in water treatment, caustic soda (sodium hydroxide, or NaOH), elevates the pH of water by absorbing both water and carbon dioxide. For all of your treatment requirements, Bell Chem, your go-to source for water treatment chemicals, keeps enough of caustic soda on hand.
