alkali's are metal hydroxides e.g magnesium hydroxide
bases are metal oxides e.g copper oxide
hydrochloric acid
HCL
sulfuric acid
H2SO4
nitric acid
HNO3
Magnesium oxide + Hydrochloric acid
Magnesium chloride + water
Copper hydroxide + Nitric acid=
Copper nitrate + water
Potassium oxide + sulphuric acid=
Potassium sulphate + water
Metal + Acid = Salt + Hydrogen
Magnesium + hydrochloric acid=
magnesium chloride + hydrogen
Copper + nitric acid
copper nitrate + hydrogen
Potassium + sulphuric acid
potassium sulphate +hydrogen
Barium + nitric acid
barium nitrate + hydrogen
Metal carbonate + acid = salt + water + carbon dioxide
Calcium carbonate + hydrochloric acid
calcium chloride + water + carbon dioxide
potassium carbonate + hydrochloric acid
potassium chloride + water + carbon dioxide
Magnesium carbonate + nitric acid
magnesium nitrate + water + carbon dioxide
A displacement reaction is a chemical reaction which a more reactive element displaces a less reactive element from its compound
zinc + lead nitrate=
zinc nitrate + lead
carbonate
CO3
making salts from insoluble alkali
Measure out 25cm3 of sulphuric acid and heat gently
remove from hear and add copper oxide until no ore will dissolve and copper oxide is in excess
the acid will have been used up now
use a filterfunnel and paper to filter off the excess copper oxide
this will leave a blue solution of copper sulphate
heatthesolutioninanevaporationbasin to remove some of the water
as the solution cools copper sulphate crystals will start to form
during neutralisation reaction (acid + alkali=salt + water), hydrogen ions (h+) from the acid react with hydroxide ions (OH-) from the base to produce water
