Which is true about the dissolving process in water?
A) Nonpolar solutes dissolve easily in water.
B)Solute molecules surround water molecules.
C)Molecules or ions of a solute spread throughout the water molecules.
D)Water molecules are repelled by solute ions at the surface of the solute.



Answer :

Answer:

C

Explanation:

Solubility between solutes and solvents depend on whether they are of same nature. So a polar solute dissolves easier in a polar solvent and vise versa. Think of it as a magnet being attracted to another magnet or metal instead of being attracted to like rubber (non polar).

Polar means an unbalanced amount of electrons on each side. So one side is negatively electrically charged if there are more electrons while the other is positive.

So since water is polar, non polar solutes wont dissolve, so not A.

B doesnt make sense. You have to have more solutes than solvent to surround water molecules.

Like I said before, water is polar and is attracted to electrically charged poles, and since ions are electrically charged particles, it will instead be attracted rather than repelled.

When molecules go in water, they get seperated into ions. So like NaCl in water would be Na+ and Cl-. I wouldnt say they wander around, but they get seperated until they get attracted to a water molecule. So B makes sense.

Hope that answered your question.
