Neutralisation resources

Students place in order, four diagrams showing the steps for making copper sulphate crystals.

Students consider the potential for chemical change when a range of everyday substances are mixed. They use logical reasoning to work out the consequences of four pairs of reactions.

Students answer three questions about information found on a bottle of bleach.

Task: Students read a pH scale to determine how it shows the increasing strength of an acid and a base solution and decide from different pH products what the effect would be on an acidic soil. Assessment focus: interpreting a pH scale.

Students use a table of some substances and their pHs to answer four questions.

Explain how to test if a solution is an acid or not, and describe and explain what happens if rusty nails are put in an acid. Assessment focus: acid reactions.

In this NEMP task students conduct a test to identify whether a number of substances are acid, base or neutral. They also answer a question about neutralising. Assessment focus: testing acid or base.
