Making Salts
Reacting an acid and a metal oxide together makes a salt. This can be separated from water through filtration and evaporation.
This is a procedure not an investigation. You could be asked to consider the size of crystals produced with different drying temperatures.
You may be asked to choose the correct acid and solid.
Hydrochloric acid = Chloride salt
Nitric acid = Nitrate salt
Sulfuric acid = Sulfate
Bunsen burner, beaker, evaporating dish, tripod, gauze, filter funnel and paper, dilute acid, metal oxide or carbonate.
Choose correct salts - How do you produce a chloride, sulfate or nitrate?
Accuracy can be improved by measuring with a balance that has a higher resolution - more decimal places.
Validity does not apply.
Does not apply.
Warm dilute acid gently.
Add metal oxide/carbonate until no more reacts (excess solid remains).
Filter to remove excess.
Evaporate the filtrate until crystals start to form, then leave to cool and dry.
