Section C Summary: 1-8

    

   1.    More sugar will dissolve in hot tea instead of iced tea because heat affects the solubility of a substance. The higher the temperature is, the more substance that can be dissolved in a solvent.

   2.    48g KCl.

   3.    Solubility of sugar:

a.    200g of sugar

b.    710g

c.    1892g

   4.      

a.    NaCl, KCl, KNO3

b.    KNO3, KCl, NaCl

   5.    Saturated means that a solution has received the maximum amount of solute that can be dissolved, while unsaturated is a solution that contains less dissolved solute than possible at that temperature.

6.    Potassium Nitrate:

a.    31g

b.    Supersaturated.

c.    70g of KNO3 should form.

   7.    More potassium nitrate:

a.    Nothing, just more solute will be in the substance, but it could become saturated if only that one crystal was needed.

b.    It will become supersaturated, or the crystal will just float to the bottom.

c.    The extra crystal will be disturbed and reform.

   8.    30% ethanol/water.
