Question 22
4 marks · Normal
Answer and see the solution →The table below shows observations from adding different metals to solutions of salts.
Observations of displacement reactions Metal added Solution Observation Zinc Copper(II) sulfate Brown solid forms; blue solution fades Copper Silver nitrate Grey crystals form; colourless solution turns blue Iron Magnesium sulfate No visible change For each reaction in the table, write the full ionic equation showing the species that change during the reaction. Where no reaction occurs, state why.
