Sodium and Potassium reacts violently with water and the metals dart about on the surface. However, if metals are wrapped in metal gauze,they can be kept underwater. A funnel is inverted over the metal gauze . A test tube full of water is inverted over the funnel. The hydrogen is given off in a steady stream, the quantity of water used should be large to prevent over-heating. in the above description, sodium is replaced with calcium but calcium doesn't have to be wrapped in metal gauze.Why?
I guess because Calcium is much more heavier!!
