Answer:
1) Loading is a process in which heavy particles settle down at the bottom of the container and water comes up . ... when alum is dropped in solution then the heavy particles of that solution becomes more heavy due to alum's chemical reacts with them and made them more heavier than before.
2)A saturated solution is a solution that contains the maximum amount of solute that is capable of being dissolved. At 20°C, the maximum amount of NaCl that will dissolve in 100. g of water is 36.0 g. If any more NaCl is added past that point, it will not dissolve because the solution is saturated.
3) Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. And, water is called the "universal solvent" because it dissolves more substances than any other liquid. ... This allows the water molecule to become attracted to many other different types of molecules
4) is that residue is whatever remains after something else has been removed while filtrate is the liquid or solution that has passed through a filter, and which has been separated from the filtride.
5) If a saturated solution is heated, then it becomes unsaturated because solubility of solute increases on heating. If a saturated solution is cooled, then some of its dissolved solute will separate out in the form of solid crystals
6) When two or more substances are mixed together they form a mixture. Components of a mixture should be separated because some components may not be useful or may spoil the useful component of the mixture.
