Calcium phase at stp
WebCalcium chloride (CaCl 2) is soluble in water and colorless. So, it exists as an aqueous solution. Therefore, you can see, white precipitate is dissolved and colorless solution is formed with time. Also, due to formation of carbon dioxide gas, gas bubbles are rising to the top of the solution. WebCalcium is a silvery-white, soft metal that tarnishes rapidly in air and reacts with water. Uses Calcium metal is used as a reducing agent in preparing other metals such as thorium and uranium. It is also used as an alloying agent for aluminium, beryllium, copper, lead and magnesium alloys. Calcium compounds are widely used.
