Chapter 7 Laboratory: Solubility and Solutions 135RQEWEvI UESTIOnS
q 1 : In this lab, we made up a 0.5 molal solution of potassium ferricyanide. What additional information would you need to calculate
the molarity of that solution? Describe at least two procedures that you could use to determine the molarity.
q: 2 After we dissolved the potassium ferricyanide, we did not rinse the beaker to transfer all of the remaining potassium ferricyanide
solution quantitatively into the storage bottle. Why?
q: 3 In what circumstances would it be useful to know the molality of a solution rather than its molarity?
