Explain with the help of an example, how an electrolyte undergo dissociation in water. what is the role play by water in formation of an aqueous solution of an electrolyte?

Answer»

When strong electrolyte like NaCl is dissolve ion water, the negative part of the water molecule start attracting the Na+ ion and positive part start attracting the Cl- ion , as these interaction are stronger than lattice enthalpy of sodium chloride ,so sodium chloride get broken into ions in solution and formed aqueous solution of the electrolyte.

 NaCl ------>  Na+ + Cl-
