Iron can be water soluble or water insoluble depending on the ionic state of iron and the compounds that it forms. Following the general solubility rules, iron is soluble when bonded to certain polyatomic ions such as sulfate and nitrate as well as halides like chlorine and bromine.Continue Reading
The ionic state of iron can affect whether the compound dissociates in water and becomes water soluble. For example, Iron II is soluble when bonded to oxalate, but Iron III is insoluble when bonded with the same polyatomic ion. Likewise, Iron III Ferricyanide is water soluble but Iron II Ferricyanide is not. Iron II and Iron III have charges charge of +2 and +3 respectively which causes them to be needed in different proportions in ionic bonds.
Iron is a trace mineral that can be found in certain types of foods and is needed for specific biological processes in the human body. Too much iron can be toxic though, so iron levels in the body should be watched accordingly. Besides food, soluble iron can also be found in water that has passed through certain pipes or has been taken out of geological sources such as ground wells. The effects of iron in drinking water can range from negligible to somewhat detrimental and can be treated using a variety of techniques.Learn more about Chemistry
Iron reacts with hydrochloric acid to produce dihydrogen and iron(II) chloride. When an HCl solution is added to iron powder, the H+ and Cl- ions from hydrochloric acid disassociate. The Cl- anions form ionic bonds with iron to form FeCl2. The H+ ions pair up, and release as hydrogen gas.Full Answer >
Citric acid is soluble in water to a great degree. In water of a temperature of 212 degrees Fahrenheit, 84 percent of the citric acid added to the solution is dissolved.Full Answer >
NaCl is soluble in water because it is an ionic crystal and when placed in water, it will undergo a dissolving reaction. NaCI is also known as a salt crystal.Full Answer >
Aluminum is insoluble in water. In addition, aluminum oxide and aluminum hydroxide, the predominate aluminum salts are considered insoluble in water. However, seawater contains between 0.013 and 5 parts per billion of aluminum.Full Answer >
