Write word equations of the reactions involved.

Answers (1)

When dilute sulphuric acid is poured on a copper plate, bubbles of hydrogen gas forms on the plate. This is because copper is metal and metal reacts with an acid to liberate hydrogen gas.

Equation:

\\ Cu\ (m) +\ H_{2}SO_{4}\ (aq)\ \rightarrow\ CuSO_{4}\ (l)\ \ \ +\ \ \ H_{2}\ (g) \\ Copper+\ \ Sulphuric\ acid \ \rightarrow Copper\ Sulphate+\ \ Hydrogen\ gas
