6) Sample questions:
 Use the terms “dilute” and “concentrated” to explain the difference between frozen juice
concentrate and juice.
 Explain how paper chromatography could be used to separate a mixture of different coloured
inks.
 List three factors that influence the rate at which dissolving occurs.
 Use the particle theory to explain why hot chocolate powder dissolves more rapidly in hot
water than cold water.
 Explain the difference between an undersaturated, saturated and supersaturated solution.
 Explain whether you would classify each of the following items as a pure substance or a
mixture: apple juice, fruit punch, distilled water, lemonade.
 Explain why a solid substance occupies less space than the same substance in its gaseous
form.
