3. In the process of crystallization, a hot saturated solution of a substance is required. This solution is then cooled down to room temperature. Chemically, why is the solution made to lower its temperature?1 pointa. To dissolve the impurities in the solutionb. To make it easier to pick up the beaker laterc. To enable the formation of crystalsd. To allow impurities to solidify in the solution

In the process of forming crystals of Copper sulphate, it is added to boiling water with a few drops of sulphuric acid and stirred continuously. This solution on cooling down yields pure crystals. Why are the crystals not formed when the solution is hot?1 pointa. Impurities would persist at higher temperaturesb. The crystals can solidify only at room temperaturesc. Salt molecules can only precipitate at the cooler temperatured. Impurities prohibit crystal formation above room temperature

When solid copper sulphate is mixed to form a hot saturated solution with water and a small amount of acid, it leads to the formation of crystals of the same compound (copper sulphate). Chemically, what is the purpose of this procedure?                                                                                                        1 pointa. To obtain a non-powdered form of the compoundb. To observe both, solid and liquid forms of the compoundc. Crystal form is easier to store and use than powdered copper sulphated. To get rid of impurities in the copper sulphate and obtain pure compound

Determine why crystals form if you evaporate water from the beaker when it contains a saturated solution.The solution already contains as much solute as it can so if solvent is removed then some of the bath salts must come out of solution as wellSaturated solutions always form crystalsRemoving solvent from any solution forms crystalsThe only way to make crystals is to add more bath saltsI'm not sure

In your own words, explain why crystals form when solvent is removed from a saturated solution.

Which of the following can be obtained by the process of crystallization, when a solution is left undisturbed for a long period of time and then allowed to evaporate to obtain pure crystals?1 pointa. Pure iron oxide (rust)b. Pure glasswarec. Crude table saltd. Crushed coffee powder
