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

The formula for crystals of hydrated copper(II) sulfate is CuS*O_{4} * 5H_{2}*O Hydrated copper(II) sulfate is made by reacting copper(II) oxide with dilute sulfuric acid,The overall equation is shown.CuO+H. S*O_{4} + 4H_{3}*O -> CuS*O_{4} * 5H_{3}*OThe crystals are made using the following steps:step 1 50c * m ^ 2 of 0.2mol / d * m ^ 2 dilute sulfuric acid is heated in a beaker. Powdered copper(II) oxide is added until the copper(II) oxide is in excess. Aqueous copper(II) sulfate is formed.step 2The excess copper(II) oxide is separated from the aqueous copper(II) sulfatestep 3The aqueous copper(11) sulfate is heated until a saturated solution is formed.step 4The saturated solution is allowed to cool and crystallise.The crystals are removed and dried.step 5Calculate the maximum mass of copper(II) sulfate crystals, CuS*O_{4} * 5H_{2}*O that can form using the following steps.Calculate the maximum mass of copper(II) sulfate crystals, CuS*O_{4} * 5H_{2}*O that can form usingthe following steps..

full reaction of copper sulphate salt by reacting copper oxide with sulphuric acid

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 required practical ‘Making soluble salts’, copper oxide is added to sulfuric acid and heated. What are the products of this reaction?Copper sulfate + water + carbon dioxideCopper sulfate + waterCopper sulfate onlyCopper sulfate + hydrogen

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 1. add excess copper oxide to dilute sulphuric acid and boil it 2. ----------- to remove the unreacted copper oxide 3.
