Calcium, Ca. Reaction with water. When a small piece of calcium is added to water, it sinks to the bottom of the water. Colorless gas bubbles evolved at a moderate rate.Unlike potassium or sodium, this experiment is safe enough to capture the gas produces, which gives a pop sound with a burning splint, indicative of hydrogen gas.alcium, Ca.
