Another name for alum

So I'm doing a lab report for AP chemistry and I need help to determine a title ... Convert this title to a college level title ..... This is the title : analysis of alum, KAl(SO4)2 12H2O ... What should I name it !??

Here's my offering:

Potassium aluminum sulfate dodecahydrate: an analysis of its chemical composition

Hope you like it.

Best wishes with your report.
