Calcium phosphide reacts with water to give 701 mL ofPH 3 collected by water displacement at 20. Magnesium phosphide react with water. Calcium, for example, reacts fairly vigorously with cold water in an exothermic reaction. Calcium is a silvery-white metal; it is relatively soft, but much harder than sodium metal.Calcium is a member of the alkaline-earth metals (Group II on the periodic table); these metals react vigorously with water, although not as violently as the Group I metals such as sodium or potassium:. =2molesof P H 3. . Wear goggles and self-contained breathing apparatus. Avoid inhalation. Reacts with water to form corrosive sodium hydroxide and phosphine a flammable poison gas Phosphine normally ignites spontaneously in contact with air If there is an excess of water this fire of phosphine will not normally ignite … It may be formed by reaction of the elements.
