There is a nice canned prelab of calculations, and the whole thing should take 25 to 30 minutes of class time to perform (10 minutes to complete the doing part of the actual experiment). The key advantage of this lab is that I have found a cheap source of reagents for it, and the reagent cost per class group to perform is something like $1.60 to $2. I was proud of that. It is robust, works great in my shed, and a rich learning experience (the colours are divine)!
