Vitamin C is a polar compound. This means...

• It can dissolve in water

• It can dissolve in oil

• It can dissolve in anything

• It can't dissolve in anything

Vitamin A is nonpolar. This means....

• It can dissolve in water

• It can dissolve in oil

• It can dissolve in anything

• It can't dissolve in anything

Polar compounds will dissolve in (select all that apply)

• Polar solvents

• Nonpolar solvents

Nonpolar compounds will dissolve in (select all that apply)

• Polar solvents

• Nonpolar solvents

According to the rule, "like dissolves like"....

• Polar solvents dissolve anything

• Nonpolar solvents dissolve anything

• Polar solvents dissolve nonpolar compounds;

  Nonpolar solvents dissovle polar compounds

• Polar solvents dissolve polar compounds only;

  Nonpolar solvents dissovle nonpolar compounds only

Which best describes the molecules that make up soap?

• Polar

• Nonpolar

• Both polar and nonpolar

• Neither polar nor nonpolar

Oil and water do not mix. What can we add to help them to mix?

• Heat

• Soap

• Pressure

• Vitamins

Molecules in soap have an ionic "head" and nonpolar "tail". Which end of the molecule will mix best with fats and greases?

• head

• tail

• the whole molecule

• none of the molecule

How do polar solvents dissovle polar compounds?

• The molecules move and slip easily amongst each other, spreading out and mixing.

• Negative ends of solvent molecules bind to positive ends of solute molecules; Positive ends of solvent molecules bind to negative ends of solute molecules

How do nonpolar solvents dissovle nonpolar compounds?

• The molecules move and slip easily amongst each other, spreading out and mixing.

• Negative ends of solvent molecules bind to positive ends of solute molecules; Positive ends of solvent molecules bind to negative ends of solute molecules
