Which is true about the dissolving process in water?

polar solutes do not dissolve easily in water.
water molecules are attracted by solute ions at the surface of the solute.
water molecules move throughout the solute. solute molecules pull water molecules away from the surface.

The statement that is true about dissolving process is that when solute is dissolved into solution. The water molecules moves throughout the solution. The solute molecules gets properly dissolved to form solution and gets uniformly distributed throughout the solution. It usually forms a homogeneous mixture in the solution.

The correct option is this: SOLUTE MOLECULES PULL WATER MOLECULES AWAY FROM THE SURFACE.

For a solute to dissolve in a solvent, the two substance must have similar inter molecular forces. When a solute is input into water, the water molecules and the solutes particles interact together to the extent that the solutes particles pull away from one another as they are surrounded by water molecules and solution is formed.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
