Silver chloride, AgCl\text{AgCl}AgCl, is an insoluble salt.
It can be made as a precipitate from a solution of silver nitrate, AgNO3\text{AgNO}_3AgNO3.
Identify a substance that could be added to silver nitrate solution to form a precipitate of silver chloride.
Write a chemical equation for the reaction between silver nitrate and the substance you identified in (a)(i).
Outline how you would produce a pure, dry sample of silver chloride from the reaction mixture in (a)(ii).
A solution of copper(II) sulfate can be made by reacting solid copper(II) carbonate with dilute sulfuric acid.
The equation for this reaction is:
CuCO3(s)+H2SO4(aq)→CuSO4(aq)+CO2(g)+H2O(l) \text{CuCO}_3(\text{s}) + \text{H}_2\text{SO}_4(\text{aq}) \rightarrow \text{CuSO}_4(\text{aq}) + \text{CO}_2(\text{g}) + \text{H}_2\text{O}(\text{l}) CuCO3(s)+H2SO4(aq)→CuSO4(aq)+CO2(g)+H2O(l)State two observations you would make when dilute sulfuric acid is added to solid copper(II) carbonate.
