(i) Copper plate reacts with sulphuric acid and forms copper sulphate and hydrogen gas and a blue colour of copper sulphate appears. (ii) \[\begin{align} & Cu\,\,\,\,\,\,\,\,\,\,+\,\,\,\,\,\,{{H}_{2}}S{{O}_{4}}\,\,\,\,\to \,\,\,\,Cu{{S}_{4}}\,\,\,+\,\,\,\,{{H}_{2}} \\ & \operatorname{copper}\,\,\,\,\,\,\,Sulphuric\,\,\,\,\,\,\,Copper\,\,\,\,\,Hydrogen \\ & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\operatorname{acid}\,\,\,\,\,\,\,\,\,\,\,\,\,\,Sulphate \\ & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,(Blue\,colour) \\ \end{align}\]
