Boiling point of hard water is more than that of distilled water at the sameatmospheric pressure. Why?5.

Answer»

This is because hard water contains sulphates, carbonates or bicarbonates of calcium and magnesium in it in the form of impurities. So these impurities actually distort the boiling point as they lead to increase in bond strength between structure and so to break the bond at boiling point larger temperature is required and as a result it has a higher boiling point. Whereas distilled water is pure H2O, and has nothingotherthan water molecules.
