Hint :The salts of magnesium chloride are typical ionic halides, being highly soluble in water. It is acidic because a weak base and a strong acid gives an acidic salt. Magnesium chloride is a polar compound. So, it dissolves in polar water but is insoluble in non- polar acetone.
Complete Step By Step Answer:
Magnesium chloride is the chemical compound with the formula . It is an inorganic salt, which is highly soluble in water.
This ion-dipole interaction between the ions and the water molecules releases energy equivalent to the enthalpy change of hydration of and . Magnesium chloride dissolves in water, the reaction gives out energy and the solution turns hot. The oxygen atoms of the water molecules face the magnesium ions, and the hydrogen atoms of the water molecules.
Solid magnesium chloride is a non-conductor of electricity because the ions aren't free to move. However, it undergoes electrolysis when the ions become free on melting. Magnesium chloride dissolves in water to give a faintly acidic solution.
So, the correct answer is .
Note :
Dissolving magnesium chloride is an exothermic process. Magnesium chloride is a hygroscopic material, able to attract moisture from the air. When more energy is released when water molecules bond to the solute than is used to pull the solute apart. Because more energy is released than is used, the molecules of the solution move faster, making the temperature increase.
