Question

Many ionic and covalent compounds dissolve well in water. This is because

the temperature of liquid water is high enough to allow anything to mix well with its fast moving particles.

the air pressure above the water is greater than the pressure exerted by the moving water particles.

the solute particles are small enough to fit in the spaces between the tightly packed solvent particles.

the attraction between the solute and solvent is about as strong as the attraction between the solvent particles.

Answer 1

even if the temperature of water is high enough it cannot break down bonds between oppositely charged ions. ionic compounds have high m.p and b.p. so they do resist high temperatures.
second option is incorrect because water is denser than air. Pressure= force/area pressure in water is greater than in air this indicates a greater force by water molecules and this is not a reason for why ionic compound dissolve.

i would go with option D. Water is a polar molecules so it comes near by an ionic compound. the \[\delta- \] oxygen are attracted to the positive ions in the ionic compound. ionic bonds breaks(solute, polar water molecules break(solvent) to form ion-ion dipole attraction.
