Which metal salt react with acid to produce carbon dioxide |
|
Answer» When acids react with carbonates, such as calcium carbonate (found in chalk, limestone and marble), a salt, water and carbon dioxide are made. The carbon dioxide causes bubbling during the reaction, which is observed as fizzing. CaCO3 metal salt react with acid to produce CO2 Reaction of acids with metal carbonate:Acids give carbon dioxide gas and respective salts along with water when they react with metal carbonates.Metal carbonate + Acid ⇨ Salt + Carbon dioxide + WaterExamples:\xa0Hydrochloric acid gives carbon dioxide gas, sodium chloride along with water when it reacts with sodium carbonate.Na2CO3\xa0+ 2HCl ⇨ 2NaCl + CO2\xa0+ H2OHydrochloric acid gives carbon dioxide, magnesium chloride and water when it reacts with magnesium carbonate.MgCO3\xa0+ 2HCl ⇨ MgCl2\xa0+ CO2\xa0+ H2OHydrochloric acid gives carbon dioxide gas, calcium chloride and water when it reacts with calcium carbonate.CaCO3\xa0+ 2HCl ⇨ CaCl2\xa0+ CO2\xa0+ H2OSulphuric acid gives calcium sulphate, carbon dioxide gas, calcium sulphate and water when it reacts with calcium carbonate.CaCO3\xa0+ H2SO4\xa0⇨ CaSO4\xa0+ CO2\xa0+ H2O CaCO3 |
