acid
substance that releases H+ ions in an aqueous solution (a proton donor)
base
substance that removes H+ ions from an aqueous solution (a proton acceptor)
strong acid
an acid that almost completely ionises/dissociates in an aqueous solution
weak base
a base that only slightly ionises/dissociates in an aquous solution
salt formed by the acids: hydrochloric acid, sulfuric acid, nitric acid
chloride, sulfate, nitrate
product formed when an acid reacts with a base
a salt and water
product formed when an acid reacts with a metal carbonate
a salt, carbon dioxide and water
product formed when an acid reacts with a metal
a salt and hydrogen
ethanoic acid
CH3COOH
Alkali
Release OH- ions in aqueous solutions Soluble in water Eg NaOH KOH
Acid + metal
Salt + hydrogen
Acid + metal oxide
Salt + water
Acid + metal hydroxide
Salt + water
Acid + metal carbonate
Salt + water + carbon dioxide
Neutralisation
Acid + metal Acid + metal oxide Acid + metal hydroxide
Redox
Acid + metal carbonate
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Any chemical compound formed from an acid when a H+ ion from the acid has been replaced by a metal ion or another positive ion E.g. ammonium ion, NH4+
Hydrated
Crystalline compounds contain water molecules
Anhydrous
Substances that contain no water molecules
H3O
Hydronium ion
Acids and bases with water
Form a reversible reaction
Polyprotic acids
Acids that can donate more than one proton
Weak base info
NH3 Backwards reaction favoured so not many OH ions produced NH3 + H2O = NH4 + OH
Strong base info
Ex NaOH, KOH Forward reaction favoured strongly. Lots of OH ions produced NaOH = Na + OH
