What are electrovalent compounds?

Electrovalent Compounds

(1). Constituent particles are ions one positively charged and other negatively charged species..

(2). They are formed by transfer of electron from a metal to a non-metal (ionic bond).

(3). They are generally solids.

(4). The ions are held by strong electrostatic forces of attraction.

(5). They are soluble in polar solvents.

(6). They conduct electricity in molten/dissolved state because in molten/dissolved state ions are free to move and conduct electric current.

(7). They undergo fast ionic reactions,

 eg. MgCl2 + Na2CO3 -----> MgCO3 + 2 NaCl
