Acids and Bases
Acids: Species that are proton donors.
When added to water, acids will release H+ ions into solution-
HCl(g) + aq -----> H+(aq) + Cl-
or H2SO4(l) + aq ----> H+(aq) + HSO4-(aq)
Bases: Species that are proton acceptors
Salts form from neutralisation reactions with carbonates, bases or alkalis.
Salt: Any chemical compound formed from an acid when a H+ ion from the acid has been replaced by a metal ion or another positive ion.
- acid + carbonate ----> salt + CO2 + H2O
- acid + base ----> salt + water
- acid + alkali ----> salt + water
