Q. Which type of polarity do water-soluble and fat-soluble substances respectively have?
Water-soluble substances are polar molecules that are they have electrically charged areas. These molecules get the explanation "water-soluble" because they are soluble in water, a polar molecule too.
Fat-soluble substances are non-polar molecules that are they are electrically neutral. They get the explanation "fat- soluble" because they dissolve other non-polar substances.
