CHEMICAL PROPERTIES OF ACID ARE ……. (1) acid react with metal to form salt and hydrogen gas.we can take some examples… Mg+2HCl———————————–>MgCl2+H2 ,here MgCl2 is salt and H2 is gas………………. (2) acid react with carbonates or hydrogen carbonates to form salt , water and CO2…… EX – 2 HCl+ MgCO3—> MgCl2+H2O+CO2….. (3) acid react with metal oxide to form satl and water.we can take some examples……… MgO+2HCl————->MgCl2+H2O.
1–Acids are sour in taste 2–When they react with bases give salt and water 3–it becomes colourless when they react phenopthalin4–are of two types # strong acids #weak acids
