Is an aqueous solution of lead (Pb) basic or acidic?
« on: January 09, 2011, 08:41:11 PM »
I am getting a lead solution at 1mg/L for my bio experiment but I am just wondering, is a heavy metal like lead acid or basic?

And how would I go about calculating this?

I don't think this concentration of lead solution would change the pH (notably) however, you can use a pH strip to confirm if it's neutral, basic, or acidic.

Why would a salt solution be acidic assuming your salt is lead nitrate?

What about hydrolysis?

Pb2+ + H2O -> PbOH+ + H+

Pb2+ + 2H2O -> Pb(OH)2(s) + 2H+
