Haha I'm gald!
will the product be a simple sugar?
Yes, because amylase breaks down starch into the sugar maltose, which is a simple sugar.
Yes that's right, thanks for helping :)
What colour will the iodine turn when it stops being blue/black??

Doesnt it have to change to Blue Black, because it is Iodine??? Red to Blue Black, it said in like 2.7 of your blog???
It will start off as blue/black as there is starch in the solution however you will know when there is no more starch as the iodine in the solution will turn a red/brown colour
