Chem 102 Lab
Week #9 (08 March 2007)

    We are now going to combine what we learned in the past two weeks - colorful coordination complexes with the equilibrium constant, Keq. Last week we measured one of the solubiliized dissociation products using thiosulfate. This week we shall measure the amount of coordination complex by the amount of color in the solution. For this we shall use a device called a spectrophotometer. The brand name is Spectronic-20.

Answers to last week's take-home.

Practice Problems
