Help with Finding Sherlock Holmes' Poison (PLEASE!!!!)
« on: October 31, 2010, 11:11:27 AM »
OK, in lab this week, we were trying to retrace the steps of Sherlock Holmes in "Sherlock Holmes and the Case of the Screaming Stepfather", and we narrowed the poison down to copper sulfate, but in the net ionic equation, the sulfate canceled out on both sides of the equation, and all we were left with was copper. So, would copper be the poison, or is it still copper sulfate? Thanks.

BTW, anyone know what Holmes identified the poison as in the story?

Heavy metal ions are quite often poisonous, nothing surprising.

I understand, I'm just wondering whether I should identify the poison as copper sulfate, or simply copper?
