When this system reaches equilibrium it is called a saturated solution , because it contains the maximum concentration of ions that can exist in equilibrium with the solid salt. The amount of salt that must be added to a given volume of solvent to form a saturated solution is called the solubility of the salt.
There are a number of patterns in the data obtained from measuring the solubility of different salts. These patterns form the basis for the rules outlined in the table below, which can guide predictions of whether a given salt will dissolve in water. These rules are based on the following definitions of the terms soluble , insoluble , and slightly soluble. A salt is soluble if it dissolves in water to give a solution with a concentration of at least 0.
A salt is insoluble if the concentration of an aqueous solution is less than 0. Slightly soluble salts give solutions that fall between these extremes.
Soluble Salts 1. The nitrate NO 3 - ion forms soluble salts. The chloride Cl - , bromide Br - , and iodide I - ions generally form soluble salts. ZnCl 2 is soluble, but CuBr is not. Many substances do not dissolve in water and that is because they are non-polar and do not interact well with water molecules. A common example is oil and water.
Steel can be dissolved with a diluted solution of nitric acid and water. The chemical make up of nitric acid reacts to the iron in steel, producing iron nitrate and hydrogen gas. As this chemical reaction takes place, the steel begins to dissolve.
Hydrochloric acid dissolves the less active metals , such as zinc and magnesium, easily. It dissolves the more-resistant iron , copper and related metals less easily, or not at all.
Other chemicals, such as nitric acid , will dissolve some metals that hydrochloric acid will not. A choking hazard is still a choking hazard, though. In general, metal oxides are basic and non- metal oxides are acidic. Some metal oxides react with water to form alkaline solutions. It is important to point out that some metal oxides do not react with water. They test neutral in water because they are insoluble but they are still bases because they react with acids.
When compounds are insoluble in water , the general reason is that the bonding within that species is stronger than bonding that could occur between it and water. Another factor that helps to determine solubility in water is how much is your solvent like water?
Iodine is basically insoluble in water. Water H 2 O is polar because of the bent shape of the molecule. The shape means most of the negative charge from the oxygen on side of the molecule and the positive charge of the hydrogen atoms is on the other side of the molecule. This is an example of polar covalent chemical bonding. Do metal oxides dissolve in water? Category: science chemistry.
