If a small crystal of a solute is added to unsaturated, saturated and supersaturated solutions, what observations do you find? Justify.
Answers
Answer:
hope this helps
Explanation:
Solution :
(i) Changes that takes place in particle size of solute in respective solutions.
(ii) Comparision of amount of solutes present in respective solutions.
(iii) Relation between changes with respect to crystal of solute and nature of the solution.
Answer:
When a solute crystal is added to an unsaturated solution, individual solute ions or compounds -- depending on the solute -- become surrounded by solvent molecules. The solvent molecules have plenty of space to reorganize themselves in such a fashion in order to dissolve the particle. Even if only one more molecule could be dissolved, the solvent molecules can quickly rearrange to accommodate the last particle before the saturation point. Any further additions, however, would have no space to squeeze into, and the particles would simply float or sink to the bottom of the container.
