Appendix III. Given the above information, after disposing of your chemical in a waste beaker or the white drum, you rinse your beaker with tap water. Can this rinse water be disposed of in the sink?
Question 22: Why is a simple plot of ion concentration vs. ion product not advisable for this type of experiment? Check all that apply.
Question 23: What do we mean by “solubility product?” Type: Multiple Choice Correct Answer(s) (in green): The reaction quotient for an ionic salt in water An equilibrium expression for the dissolution of an ionic salt The criteria for dissolution of an ionic solid The product of a solubility experiment
Question 24: Which one of the following will affect the value of a solubility product constant?
Question 25: The correct procedure for preparation of a buret for titration of a strong acid with a strong base: 1.First clean the buret with approved laboratory glassware cleaner and a buret brush (if available). 2.Rinse
the interior of the buret with tap water (one time). 3.Rinse the interior of the buret with deionized water (one time). 4.Rinse the interior of the buret with about 5mL of your titrant, dispose of this aliquot in your waste beaker. To properly wet the inside surfaces, tip the buret on its side while holding it in your hand. Be careful not to spill the solution (you can use parafilm to cover the open end of the buret). Make sure the solution comes into contact with every surface in the interior of the buret by rotating the buret. Drain the rinse solution through the stopcock into the waste beaker. 5.Rinse the
