Properties of Electrovalent Compounds:

Crystal Structure: In the solid state of electrovalent compounds, anions and cations are arranged in a regular manner. This is a crystal in which anions are surrounded by a definite number of cations and vice-versa.

Physical Nature: Ionic or electrovalent compounds are generally hard. Their hardness increases with increasing ionic charge and the decreasing distance between ions.

Solubility: Positive ion of ionic compound attaches to the negative part of a polar solvent and negative ion of ionic compound attach with the positive part of the polar solvent. Therefore, ionic or electrovalent compounds are soluble in polar solvents like water and insoluble in non-polar solvents like benzene, ether, alcohol.

Melting Point and Boiling Point: Electrovalent or ionic compounds have high melting and boiling points because they need a large amount of energy to break strong ionic bonds.
