C.5 Problems #1-3
1.
a. Nothing
would happen to the solution if the beaker remained undisturbed and no more KCl
was added. If one crystal of KCl was added the extra solutes would become
precipitate, and the solution would rebalance itself.
b. See
drawing
2. See drawing
3.
a and b: See
drawings.
c. In 3a, the
concentration of the solution expressed as a percent KCl by mass is 10%. Since
the amount of water is double in 3b, 10g/200g X 100% = 5%. The percent
concentration of 3a is 10%, where as the percent concentration of 3b is 5%.
