When a mixture of two black powders is heated, it gave off a gas which turned lime water milky
Give a chemical equation to show the reaction between gas and lime water
Red scales residue can be seen on the black residue. Name the red scales
The red scale residue partly dissolves in dilute acid to form a pale blue solution. Name the pale blue solution and give chemical equation to support your answer.
