Solution

Salt $S$ is prepared by reacting dilute sulphuric acid with copper oxide. Hence, salt $S$ is copper sulphate. That is, when dilute sulphuric acid reacts with copper oxide the salt produced is copper sulphate.

The balanced chemical reaction is shown below.

$C u O + H_{2} S O_{4} \to C u S O_{4} + H_{2} O$
