Illustrate any three chemical properties of acid witg examples? |
| Answer» Reaction of acids with metal: Acids give hydrogen gas along with respective salt when they react with a metal.Hydrogen gas and zinc chloride are formed when hydrochloric acid reacts with zinc metal.Zn + 2HCl → ZnCl2 + H2Reaction of acids with metal carbonate:Acids give carbon dioxide gas and respective salts along with water when they react with metal carbonates.Hydrochloric acid gives carbon dioxide gas, sodium chloride along with water when reacts with sodium carbonate.Na2CO3 + 2HCl → 2NaCl + CO2 + H2OReaction of acid with hydrogen carbonates (bicarbonates): Acids give carbon dioxide gas, respective salt and water when they react with metal hydrogen carbonate.Hydrochloric acid gives carbon dioxide, sodium chloride and water when it reacts with sodium bicarbonate.NaHCO3 + HCl → NaCl + CO2 + H2O\xa0 | |
