What is EDTA? | Sciencing
Jun 04, 2019· EDTA is a dry, white crystalline powder. EDTA is a hexadentate ligand, which means that it creates 6 bonds with a central metal ion.When it bonds with a calcium ion, it becomes EDTA calcium disodium. EDTA calcium disodium can then chelate other metal ions by exchanging its calcium ion for another metal ion that has a greater affinity for the EDTA molecule.

Metal Profile: Iron Properties and Characteristics
Jan 12, 2020· Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.
Calcium - Periodic table
Calcium reacts easily with water and acids and the metal burns brightly in air, forming mainly the nitride. Uses of Calcium. Calcium forms alloys with aluminum, beryllium, copper, lead, and magnesium. It is used in the manufacture of other metals such as uranium and thorium. Calcium is used to remove oxygen, sulfur and carbon from alloys.
