typical reactions of acids

General equation of acids with metals

metal + acid --> salt + hydrogen

Observation of acids with metals

bubbles of hydrogen form

General equation of acids with metal oxides and insoluble metal hydroxides

metal oxide/hydroxide + acid --> salt + water

Observations of acids with metal oxides and insoluble metal hydroxides

formation of a solution

Alkali

metal hydroxide dissolved in water

General equation of acids with alkalis

alkali + acid --> salt + water

Observation of acids with alkalis

temperature rise

General equation of acids with carbonates

metal carbonate + acid --> salt + water + carbon dioxide

Observation of acids with carbonates

bubbles of carbon dioxide form. if the salt formed is soluble, then a solution forms

General equation of acids with hydrogencarbonates

metal hydrogencarbonate + acid --> salt + water + carbon dioxide

Observation of acids with hydrogencarbonates

bubbles of carbon dioxide form. if the salt formed is soluble, then a solution forms

Test and observation for carbonates and hydrogen carbonates

Add an aqueous acid. Bubbles of a gas (carbon dioxide) which turns limewater milky is produced.
