Chemistry Revision: Reactivity Series Metals and Acid Reactions Year 8 Week 11
Metal and Acid Reactions WALT: discover the reactivity series of metals by reacting them with acids I must be able to state the equation for reacting a metal and an acid I should be able to carry out a practical to discover the reactivity series I might be able to write out the full word equations for these reactions
Last lesson we learnt the gas tests for…. Oxygen………….. Carbon dioxide …………. Hydrogen…………..
Can you remember how to form a salt? Acid + alkali >>>>> salt + water
A salt is ….. Something formed from an acid…… Table salt (sodium chloride) is just one example
You are going to make some salts 1. 2. Acid Metal
Metals we will use are: Magnesium Zinc Iron Aluminium Copper Lead
Check your answers with page 232 of the books Metal Reaction with acid (how vigorous, fast etc) Gas produced Magnesium Zinc Iron Lead Aluminium Copper The more reactive metals will react more vigorously. Use your results to put the metals in order of reactivity. Check your answers with page 232 of the books Write a method, results and conclusion See if you can write out the full word equations for the reactions that have taken place
acid + metal >>> salt + hydrogen e.g. magnesium + hydrochloric >>> magnesium + hydrogen acid chloride
Plenary What did the results tell you about the reactivity series How could we have made the results more reliable? 2. Tried with different acids
