In its elemental form, calcium has a dull gray-silver appearance. Calcium is a reactive, soft metal that is a meer of the alkaline earth elements. It frequently serves as an alloying agent for other metals like aluminum and beryllium industrial materials like cement and mortar are composed of calcium compounds like calcium carbonate .

Reactions of metals with acids producing salts | …

Many, but not all, metals react with acids. Hydrogen gas forms as the metals react with the acid to form salts. This class experiment is often used in the introductory study of acids to establish that this behaviour is a characteristic property. The experiment is done first on a smaller scale using test tubes (lesson 1 below), with no attempt

Heavy Metals: Oxidation and Metal Staining

Water is the universal solvent, and can eventually dissolve just about anything. Yes, this includes metal minerals like calcium and magnesium, and it also includes heavy metals like copper, iron, manganese and silver. Unlike minerals (calcium and magnesium), heavy metals are oxidants, which means they get oxidized in the presence of chlorine.
