Also doing the coursework for AS biology involving egg albumen and copper sulphate solution. Maybe being really dumb but we are only given one concentration of solution so wot measurements of solution and water do we use to make less concentrated solutions??

Hope someone can help me out. Thanx.

My teacher said use concentrations ranging from 0.01 to 0.1. Apparently the actual answer is 0.03 or sumthing. Hope this helps. I'm seriously stuck on this too!! Luv Sam x
