	What are the common properties of acids? (6)	They are Covalent Molecular Taste Sour Are Corrosive Turn blue litmus red when dissolved in water they IONISE are neutralised by bases
	A reaction of an acid and metal will produce..?	Salt and hydrogen gas
	A reaction of an acid and base (metal hydroxide) will produce..?	Salt and water
	A reaction of an acid and metal carbonate will produce..?	Salt, carbon dioxide and water
	A reaction of an acid and metal hydrogen carbonate will produce..?	Salt, carbon dioxide and water
	A reaction of an acid and metal oxide will produce..?	Salt and water
	What are the common properties of bases? (6)	Most bases are IONIC yet some are MOLECULAR COVALENT Taste Bitter Feel slippery May be corrosive Turn red litmus blue when dissolved covalent molecular bases ionise, and ionic bases dissociate
	STRONG ACIDS readily donate their proton and thereby...	completely ionise!
	examples of some strong acids are..	Hydrochloric acid, sulfuric acid and nitric acid
	Weak acids only partially ionise. An example of aweak acids is..	Ethanoic acid (acetic acid)
	WHICH STRENGTH OF BASE completely dissociates in water, breaking apart into positive and negative ions, then in the case of an oxide ion, completely reacts with water by accepting a proton to form the hydroxide ion.	STRONG bases.
	Weak bases like ammonia only ____________ ionise in water	Weak bases like ammonia only partially ionise in water
