dissolving ionic salts

The ionic crystals consist of positively and negatively charged ions arranged in a regular fashion throughout the crystal. They form a network of positive and nagative ions in three dimension in such a way that cations and anions occupy alternate sites. These are held together by strong ..

"A salt is an electrovalent compound, made up of a positive ion other than a hydrogen ion (H + ) and a negative ion, other than a hydroxyl ion (OH - ). When dissolved in water, it dissociates into free mobile ions." Such salts thus behave as electrolytes. They can be ..

Elements of groups 1, 2, 10, 11, 12, 13 and some lanthanides form ionic carbides. These carbides react with water liberating lower hydrocarbons. Calcium carbide (CaC 2 ), Beryllium and aluminium carbides (Al 4 C 3 ) and magnesium carbide (MgC 2 ) are examples of ionic carbid..

The ionic compounds split up into oppositely charged ions when dissolved in water. The chemical reactions of ionic compounds are characteristic of the constituent ions and are known as 'ionic reactions'. Such reactions occur almost instantaneously.For exampl..

Suppose we dissolve silver nitrate, an ionic solid in water, the ions in the crystal lattice are released and once in solution, move freely in hydrated form. The situation is represented by the equatio..

When salt is added to boiling water the temperature of boiling water is raised above 100 o C. This is because the salt absorbs heat energy from the water for dissolving in it and its average kinetic energy decreases. When gases dissolve in water it lowers th..

Dissolution of different salts in water does not always result in neutral solutions. For example, aqueous solution of copper sulphate is acidic whereas aqueous solution of sodium acetate is basic and aqueous solution of sodium chloride forms neutral solution. This is due to the dissociati..

Salt Formation - Amines being basic react with acids to form salts. Salts of amines are typical ionic solids. Amine salts are soluble in water but insoluble in non-polar solvents. The aqueous solutions of these amines on treatment with aqueous hydro..

Ionic solids are hard and brittle. Ionic solids dissolve in polar solvents like water "The ions of the ionic solids are pulled out of their lattice sites by the dipole movement of the polar solvent and dispersed into solvent form in the solution. ..

An ionic or electrovalent bond has the following characteristics: An ionic bond is formed due to the coulombic attraction between the positively and negatively charged ions. An ionic bond is non-directional i.e., the strength of interaction between two ions depen..
