Re: Investigating a metallic element
Did you use distilled water to make the Agar . If you used Tap water , could be Chlorine reacting with the Silver Nitrate .
EDIT: I have not done that Prac myself , was just a thought .

I put out distilled water, but I'll check with the teacher. Thanks for your time.
