Effect of lead nitrate on amylase
1 student responses
Should workers in a Lead Mine, who may get varying concentrations of lead on their clothes, be given special instructions about how to wash their clothes when using washing powders that contain bacterial amylase?
That was the original question.
She said that jsut assessing the change in colour may be too simple for an A-Level coursework.
I was originally going to add starch , lead nitrate and amylase to a test tube, and put it into a 35 0C water bath. I was going to repeat this 5 times with varying concentration of lead nitrate to see its different effects.
After leaving it in the water bath for 5 minutes, I would place a small sample of the solution into a cuvette, and then add iodine to it. I would then place the solution into a colorimeter to see its density.
I am really not sure how else to conduct this experiment in a more complex way?
