Question

1. The introduction of chemical, physical or biological materials that degrades the quality of fresh or sea water, such that it is harmful to the organism living in it or consuming it is called (water degradation/water pollution] 2. When a saturated solution at some temperature is cooled by 10°C to 20°C it forms its own (supersaturated solution/crystals 3. During crystallisation as saturated solution always [remains saturated/becomes unstaurated) 4. The solubility does not change with the rise in temperature of the solution. (sodium chloride solution/sodium nitrate solution 5. The amount of solute (by weight), present in a given weight of a solution is called its (solubility/concentration​
