Students use their knowledge from the unit to compare a range of pH indicators in terms of effectiveness in identifying a range of pH in everyday household products.
Students compare red cabbage indicator (prepared in a previous lesson), litmus paper, universal indicator solution and pH probes to decide which one is the most accurate and easy to use.
