Are Ionic Bonds Soluble

May 4, 2013

Introduction to ionic compounds solubility:

Solubility is the process of a solid, liquid, or gaseous chemical substance. The solid, liquid and gas together are called as a solute. A solute is a solvent used to dissolve a homogeneous solution of the solute present in the solvent. The solubility of a substance basically depends on the solvent used as well as lying on temperature and pressure. The amount of the solubility of a material in an exact solvent is calculated as the saturation concentration. Upon more addition of solute does not increase the concentration of the solution. The solvent is usually a liquid, which can be either a pure substance or a mixture.

The ionic compound degree of solubility ranges widely, from considerably soluble (fully miscible), such as ethanol in water, to badly soluble, such as silver chloride (AgCl), in water. The word insoluble is often applied to weakly or very badly soluble compounds. Under suitable conditions the equilibrium shifts such that the solubility can be exceed to give a supersaturated solution, which is Meta stable. Solubility does not occur only with the ability to dissolve or liquefy a substance, they might also occur because of dissolution but also due to a chemical reaction.

For example, zinc is insoluble in HCl, but does dissolve in zinc chloride and hydrogen due to the chemical reaction, where zinc chloride is further soluble in hydrochloric acid.

Solubility of ionic compounds

Ionic compound soluble classification:

Ionic compounds Soluble are generally classified into polar and non polar compounds. The existence of polar and non-polar molecules depends upon the following reasons: A non polar solution contains molecules that are uniformly charged on all sides of the molecule. Essentially, these molecules keep to themselves and they do not relate with other charged molecules, because they are already stable and neutral molecules.

On the other hand, in a polar solution, molecules have a difference charges across the molecule. Thus, the bottom of the molecule may be more negatively charged than the top of the molecule, due to the difference in electro negativity of the atoms. Thus, if we add some ionic compounds (ionic compounds are compounds that are charged) together with polar molecules, they will easily wind up, because they both hold charges and can therefore attract each other.

As a result, ionic compounds soluble can mix and liquefy only into a polar solution, they are so because a polar solution contains molecules that carry comparative charges, and seems to be ionic. Thus, they get attached easily to these relatively charged polar molecules, and can therefore mix with them and dissolve into the solution.

Are ionic compound soluble in water

Some of the ionic compounds gets easily dissociated with water whereas some other compounds do not?

On the other hand, the solubility of the ionic molecules depends on the equilibrium forces between the ions present in the salt and between the ions in the solute molecules, the presence of ions in the solute molecule is greater than the former the salt dissolves easily in this case. Thus, the energy needed to split the ionic bonds in that salt is lesser than that released; the ions so formed cooperate with the solvent molecules. Similarly if they are not soluble they get precipitated from the solution.
