Q.4. Give reasons :
1. Distilled water is flat to taste
2. Hard water is not suitable for boilers.
3. Hard water is good for healthy teeth and bones.​

Answer 1

Answer:

1. Boiled or distilled water does not have any minerals, salts, or dissolved gases in it hence it tastes flat.
2. Hard water contains dissolved salts of calcium and magnesium. It forms scales (also called lime scales) on the walls of the boilers and hence to be softened before its usage in industries. These scales reduce the heat conductivity of boilers some times leading to the breakdown.
3. For the most part, the minerals in hard water tend not to be abrasive enough to damage your teeth or their enamel. Using a store-bought water filter will help to cut down on the buildup of mineral deposits in your appliances, but you don't need to worry about the condition of your teeth.
