Textbook Question
Chapter 4, Problem 130CP
Three students were asked to find the identity of themetal in a particular sulfate salt. They dissolved a0.1472-g sample of the salt in water and treated it withexcess barium chloride, resulting in the precipitation ofbarium sulfate. After the precipitate had been filteredand dried, it weighed 0.2327 g.
Each student analyzed the data independently andcame to different conclusions. Pat decided that the metalwas titanium. Chris thought it was sodium. Randy reportedthat it was gallium. What formula did each studentassign to the sulfate salt?
Look for information on the sulfates of gallium, sodium,and titanium in this text and reference books suchas the CRC Handbook of Chemistry and Physics. Whatfurther tests would you suggest to determine which studentis most likely correct?

In the Thermo Fisher application note about wine analysis (Lesson 3), the following
chromatogram was collected of nine components of wine. If peak 3 has a retention time of
3.15 minutes and a peak width of 0.070 minutes, and peak 4 has a retention time of 3.24
minutes and a peak width of 0.075 minutes, what is the resolution factor between the two
peaks? [Hint: it will help to review Lesson 2 for this question.]
