Calcium - MMTA

24/6/2016· Calcium, when in contact with air, decomposes quickly into calcium hydroxide and calcium carbonate, which are both chalky, white substances. On contact with water or acid, calcium metal generates hydrogen gas, similarly to the Alkali Metals of Group 1, but does so at a slower, more controlled pace, making it a useful source of small amount of hydrogen.
