Illustrate any three chemical properties of acids. With examples.

Explanation

They react with metals to give out hydrogen gas , e.g .,
`underset("Zinc")(Zn)+underset("acid")underset("Hydrochloric")(2HCl) tounderset("chloride")underset("Zinc")(ZnCl_(2))+underset("Hydrogen")(H_(2))uarr`
(ii) They react with metals to give out hydrogen gas , e.g.,
`underset("Zinc")(Zn)+underset("acid")underset("Sulphuric")(H_(2)SO_(4))tounderset("sulphate")underset("Sodium")(Na_(2)SO_(4))+underset("water")(2H_(2)O)`
(iii) They react with metal carnonates to liberate carbon dioxide gas , e.g., `underset("hydroxide")underset("Sodium")(Na_(2)CO_(3))+underset("acid")underset("Hydrochloric")(2HCl)tounderset("Water")(H_(2)O)+underset("dioxide")underset("Carbon")(CO_(2))`
