Reactions of Group 2 Elements with Water - …

12.07.2019· Calcium, Strontium, and Barium. These metals react with cold water with increasing vigor to give the metal hydroxide and hydrogen. Strontium and barium have reactivities similar to that of lithium. Calcium, for example, reacts fairly vigorously and exothermically with cold water.

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.

The very active metals react with water. For example, calcium reacts with water to form calcium hydroxide and hydrogen gas. Calcium metal has an oxidation nuer of 0, whereas Ca 2+ in Ca (OH) 2 has an oxidation nuer of +2, so calcium is oxidized. Hydrogen''s oxidation nuer changes from +1 to 0, so it is reduced.

Causes of Corrosion - Water/Wastewater …

In general, corrosion is the result of water with a low pH. Acidic waters have lots of H + ions in the water to react with the electrons at the hode, so corrosion is enhanced. In contrast, water with a higher pH (basic water) lowers the solubility of calcium carbonate so that the calcium carbonate is more likely to precipitate out as scale.
