Calcium reacts with water, 2 of 3. Calcium metal (Ca) reacts vigorously with water (H2O), producing hydrogen gas (H2) bubbles and slightly soluble calcium hydroxide (Ca(OH)2): Ca + H2O -> Ca(OH)2 + H2. In this sequence a chunk of calcium is dropped into a test tube with water. Calcium first sinks but then bubbles up due to H2. Calcium hydroxide is seen as white precipitate. | |
