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.Know More
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
Hydrogen gas is sparingly soluble in water. At 25 degrees Celsius and a partial pressure of one atmosphere, hydrogen gas has a mole fraction solubility of 0.00001411 in pure water. A liter of water dissolves about 0.00078 moles of hydrogen at a partial pressure of one atmosphere.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 >
KCl, potassium chloride, is a compound made up of the alkali metal potassium and chlorine, and it is soluble in water. In an aqueous solution, KCl separates into K+ and Cl- ions.Full Answer >
Barium sulphate, or BaSO4, is insoluble in water. It is a white crystalline solid. Barium sulphate is an odorless organic compound that is insoluble in most acids and bases and only soluble in hot, concentrated sulfuric acid. Barium sulphate is not considered toxic.Full Answer >
