For example, if a precipitate is colored or appears gelatinous, a comment to that effect should appear on your worksheet. Part B: Inves tigating Some Exceptions to the Solubility Rules 1 In two of the unused wells of your well plate, mix the solutions listed in Table B, as you did for Part A. 2 Record your observations in Table B. If a precipitate forms, put Y in the space that corresponds to the two solutions that were mixed. If no reaction occurs (no precipitate forms), put an N in the appropriate space in the table. If you cannot see a result clearly in the well plate, repeat the experiment in a small clean test tube. 3 When you are finished, collect all your waste and deposit it in the waste container provided on the side shelf. Use a minimum amount of water to rinse residual solutions into the waste container. Then clean and dry all your equipment and return it to the set- up area where you found it. 4 Before leaving, go to a computer in the laboratory and enter your results in the In- Lab assignment. If all results are scored as correct, log out. If not all results are correct, try to find the error or consult with your lab instructor. When all results are correct, note them and log out of WebAssign. The In- Lab assignment must be completed by the end of the lab period. If additional time is required, please consult with your lab instructor.
