• 104.5 °C

• 105.5°C

A student sets up the following apparatus for an experiment.

What are X and Y?

• X is balance; Y is burette

• X is burette; Y is pipette

• X is burette; Y is balance

• X is pipette; Y is balance

A series of experiments was carried out in order to determine how the rate of dissolving sugar in water varied with the temperature of the water. In each experiment, 10 g of sugar was dissolved in 50 cm³ of water of varying temperatures in beaker.

Which four pieces of apparatus would be needed to carry out the experiment?

• 1, 2, 3 and 4

• 1, 2, 3 and 5

• 2, 3, 4 and 6

• 1, 3, 5 and 6

What is the correct arrangement of steps involved in crystallisation?

 

I     Test for saturation of solution by dipping a clean glass rod into the solution.

II    Filter the solution to collect the crystals, then wash and dry them.

III   Heat the solution in an evaporating dish.

IV   Leave the solution to cool.
