2 Acids and Metal Carbonates Experiment Aim: To investigate the reaction between metal carbonate and acids.Method:LimewaterAcidMetal Carbonate
3 Effect of gas produced on Results:Effect of gas produced onReactionLimewaterSodium Carbonate + ________Copper carbonate + _________Conclusion:Carbonates react with acids to produce CO2(g) which is an acidic gas.
4 Acids and Metal Carbonates Carbonate rocks are used in a lot of buildings. When acid rain falls on these buildings the acid reacts with the carbonate in a neutralisation reaction.Metal Carbonate +Acid Salt+Water+Carbon dioxideCalcium carbonate Calcium chloride++Hydrochloric acid water+carbon dioxideCaCO3 + HCl CaCl2 + H2O + CO2
6 Magnesium carbonate+ Magnesium chloride hydrochloric acid water +carbon dioxideMgCO3 + HCl MgCl2 + H2O + CO2In these reactions the H+ of the acid reacts with the CO3- ions of the metal carbonate to form water and carbon dioxide. The H+ ion is replaced by the metal ion: Neutralisation reaction.
