APPARATUS
REQUIRED
PRACTICALS dilute sulfuric acid
a measuring cylinders
copper (II) oxide powder
a spatula
AIM
a glass rod
a 100 cm3 beaker
Making soluble salts: preparation of a 250 cm3 beaker
pure dry copper sulphate crystals a Bunsen burner
a tripod
gauze
VARIABLES
a heatproof mat
a filter funnel and paper
Independent variable: the metal a small conical flask
oxide (or carbonate) that is used an evaporating basin
a crystallizing dish.
Dependent variable: the salt
produced
Control variables: fixed volume of
sulfuric acid (the limiting reactant in METHOD
the equation), the acid used
1: SALT MAKING 1. Measure 40 cm^3 sulfuric acid and put into
the 100 cm^3 beaker
2. Set up the Bunsen burner, tripod, and
POSSIBLE QUESTIONS: heatproof mat: put the beaker on the gauze
“Describe a method to make and heat the acid gently until it is almost
pure, dry crystals of
magnesium sulfate from a
metal oxide and dilute acid”
- Be as specific as
possible
- Include variables
- Follow a logical
sequence
boiling. Turn off the Bunsen burner
3. Remove the beaker from the tripod and add
small amount of copper (ii) oxide using a
spatula to acid, stir with a glass rod until it is
dissolved, and the solution is blue
4. Keep repeating the previous step until the
solution is super saturated and no more
