Question 78
An investigation into the reaction of metals in acid
Sofia and Marcus have been asked to investigate the reactivity of metals with acids. They need to decide on which of the equipment and reagents they need. The metals shown are sodium, potassium, magnesium, calcium, zinc, copper and iron in the form of blocks, filings or powder.
Part 1: Planning the investigation
Plan the investigation for Sofia and Marcus. Choose which of the items in the diagrams they need to use. Some of the items are not appropriate to use.
Discuss in your small group how you will answer these questions.
• What will they change?
• What will they keep the same?
• How will they measure the reactivity and decide which is the most or least reactive metal?
• How will they keep safe?
• What equipment will they use?
Remember to include a results table and an idea of what they should be looking for in order to identify which are the most reactive metals.
Write your plan and show it to your teacher.
