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. Heat the solution until it is -------------------4. ------------ the solution to form ---------------coloured crytsal of copper

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

1. add excess copper oxide to dillute​ sulphuric acid and boil it 2. Filter to remove the unreacted copper oxide 3. Heat the solution until it is White4. Saturate the solution to form blue coloured crytsal of copper oxide

In the core 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 + hydrogenCopper sulfate + waterCopper sulfate only2In the core practical ‘Making soluble salts’, how do we ensure that all the acid completely reacts?By heating the solutionBy filtering the solutionBy adding excess copper oxideBy stirring the solution3In this practical, why is the mixture filtered once the reaction has completed?To remove excess copper oxideTo remove impuritiesTo remove excess copper sulfateTo remove the water4After filtration, why is the remaining salt solution heated?To evaporate the water from the solutionTo make the solution turn blueTo ensure the reaction has completedTo remove hydrogen gas from the solution5After heating, what would you expect to observe as the hot saturated solution begins to cool?Solution changes from clear to blueFormation of blue crystalsBubbling/fizzing in solutionFormation of white crystals

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

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
