Caption: Calcium reacts with sulfuric acid, 3 of 3. In this sequence a chunk of calcium metal (Ca) is dropped into a test tube with 0.1 M sulfuric acid (H2SO4). Calcium reacts vigorously with the acid producing hydrogen gas (H2) bubbles and insoluble calcium sulphate seen as white precipitate. Calcium first sinks but then bubbles up due to H2. The reaction is: Ca + H2SO4 -> CaSO4 + H2.
