Heavy Metals Toxicity and the Environment

Heavy metals are naturally occurring elements that have a high atomic weight and a density at least 5 times greater than that of water. Their multiple industrial, domestic, agricultural, medical and technological appliions have led to their wide distribution in the environment; raising concerns over their potential effects on human health and the environment.

Tests for carbonate ion, compounds, reactions, precipitates

test the presence of Carbonate ions in water. Check pH value. Metal carbonate compounds are usually weak bases. So pH value is slightly over the 7. But this test is not enough to prove the presence of carbonate ion. Therefore, add aqueous calcium chloride solution to the carbonate ion solution. You will see a white precipitate forms. (CaCO 3).

Flame tests using metal salts | Resource | RSC Eduion

Record the metal salt solution and the flame colour. Repeat steps 2 to 4 for each of the other metal salt solutions you have been provided with. Theory: Calcium ethanoate is a very hygroscopic solid. This means it absorbs and coordinates with water very easily.

How Was Calcium Discovered?

Mar 30, 2020· Sir Humphry Davy discovered calcium in 1808 by isolating the impure metal through the electrolysis of a lime and mercuric oxide mixture. He accomplished this by studying the preparation of calcium amalgam through the electrolysis of lime in mercury. The term calcium comes from the Latin word calx, which means lime.
