ACIDS BASES AND SALTS
bases
metal oxides or hydroxides
alkalis are soluble bases (metal hydroxides)
disassociate to form oh- ions
proton acceptors
strong alkali - fully ionises and vice versa
properties
soapy
conduct electricity
corrosive if concentrated
turn red litmus blue
acids
proton donors
disassociate into h+ ions when dissolved in water
strong acids - hydrochloric acid
weak acids - ethanoic acid
properties
sour taste
conduct electricity
corrosive if concentrated
turn blue litmus red
oxides
basic oxides
metal combines with o2
except lead, zinc, aluminium
react with acids to form salt and water
amphoteric oxides
metal combines with oxygen
example - lead, aluminium, zinc
reacts with acid or base to form salt and water
salts
soluble
titration
adding excess
insoluble
precipitation
