InterviewSolution

1.	Why is hard water not used in industrial boilers?
Answer» Hard water contains calcium and magnesium soluble salts. If it is used in industrial boilers, it forms insoluble salts of calcium and magnesium. They produce scales on the inner walls of the boilers, which reduce heating efficiency. There is a chance of explosion of boilers due to foaming. It also corrodes the boilers.
