Describe and explain the stages in making copper chloride crystals from an insoluble base and an acid
Answers
Add excess copper carbonate to hydrochloric acid in a beaker, stirring until there is no further reaction. Filter the mixture to remove the remaining copper carbonate, then heat the remaining solution to the point of crystallisation. Leave the solution to cool and collect the crystals formed by filtration. The first part comes from the metal, metal oxide or metal carbonate. The second part comes from the acid: hydrochloric acid produces chloride salts. nitric acid produces nitrate salts.
its the answer..
