How do you produce copper sulphate salt crystals?
1- Heat mixture of excess base and acid 2- filter the salt and excess base solution to remove insoluble base 3- then let aqueous salt solution evaporate
What salts are made from hydrochloric acid, nitric acid, sulfuric acid
copper hydrate salt crystals, copper nitrate sulphate salt crystals, copper sulphate salt crystals
How do you test for sulphate ions ( SO4 2‒)
• By adding Barium Chloride - A white precipitate of barium sulphate forms if sulphate ions are present
Why is titration used?
to determine relative and actual concentrations of solutions of acids/alkalis
solid
mass = moles x mr
liquid
moles= conc x vol/1000
What unit do you use for concentration?
Mol dm-3
