#### potassium | Definition, Properties, & Reactions | Britannica

Potassium metal is soft and white with a silvery lustre, has a low melting point, and is a good conductor of heat and electricity. Potassium imparts a lavender colour to a flame, and its vapour is green. It is the seventh most abundant element in Earth’s crust, 2.6

#### What happens when acid reacts with limestone? | …

15/6/2008· Answer. Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don''t dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve.

#### explain why calcium metal after reacting with water starts …

30/3/2021· The reaction of calcium with water is less violent. SO, the heat released is not sufficient for the hydrogen to ch fire. Calcium starts floating because the bubbles of hydrogen gas which are formed during the reaction stick to the surface of the metal and hence calcium floats on water.
