Arsenic Acid is a compound made up of arsenic and oxygen. It is acidic and has an activation energy of 15.6 kcal/mol, a thermodynamic data of -121.5 kJ/mol, and a neutral ph. Arsenic acid reacts with sodium hydroxide solution to form sodium arsenite and hydrogen gas. This reaction is exothermic, meaning that it releases heat. The dry weight of arsenic acid is 1.07 grams per mole and the metal hydroxides are calcium (1:1) and magnesium (2:3). X-ray diffraction data shows that calcium has low energy peaks at 13 degrees, 16 degrees, 18 degrees, and 20 degrees. A membrane system can be used to remove arsenic from wastewater treatment by using an anion exchange resin in conjunction with an organic co-solvent such as methanol or acetonitrile.
