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

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

A student wanted to prepare copper(II) sulfate crystals by reacting solid copper(II) oxide to a solution of hot sulfuric acid. An extract from the method section of the experimental handout is shown below: Add the copper(II) oxide in small amounts to the hot acid in the reaction flask and stir until it is …..1….. When the reaction has gone to completion the copper(II) oxide will no longer …..2….., …..3….. and …..4….. the solution to obtain the copper(II) sulfate crystals. 1 2 3 4 A in excess precipitate cool dissolve B in excess dissolve filter cool C reacting dissolve cool filter D reacting precipitate filter coo

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

The salt copper sulphate can be prepared by reacting copper oxide with sulphuric acid complete the list of instructions for making copper sulphate down below are six words blue,saturate, dilute, filter, white and oxide add excess copper oxide to ---------- sulphuric acid and boil it

A certain inorganic compound (A) on heating loses its water of crystallization. On further heating, a blackish brown powder (B) and two oxides of sulphur (C and D) are obtained.
