Q

non electrolyte

A

cannot conduct electricity at all (covalent bonded solutes are dissolved in water since they don’t split up)

17
Q

colligative properties

A

property that is affected by the solute particles in the solution

18
Q

colligative properties ex

A

VP goes down
BP raises
FP goes down

19
