Title: amphoteric "elements"
Post by: zephyrblows on June 18, 2007, 10:35:37 PM

I know some metal (hydr)oxides are amphoteric, but my teacher said the metals having amphoteric (hydr)oxides can react with SA / SB THEMSELVES and produce H₂.

Uh, why?
For example, Pb and Sn don't seem to be strong enough to reduce H₂ out, do they? ???

Thanks a lot!
