Question

When salt is added to water, salt solution is formed by the process of diffusion but when salt is in contact with air it's particles do not get into the molecular spaces between air particles. But air particles move more rapidly than water particles and there is more intermolecular space between the air particles than the water particles. Why does thi happen ?

Answer 1

Salt ionises in the presence of water and dissociates to form solution while this is not possible in air even though they move very rapidly. Moreover water is a polar solvent and air is mixture of gases.

Answer 2

Answer:

Water is a solvent in which salts get ionised or we can say dissociate to form ions so their conductivity i.e. movement increases but air donot ionise salt and salt is present in solid state so it didnot move as it move in water.
