Using the following spontaneous reactions, classify the 3 metals involved (Cr, Sn, Al) according to increasing reductant properties.
a)2Cr + 3Sn2+ ->2Cr3+ + 3Sn
b)Al + Cr3+ -> Al3+ + Cr
HELP HARD CHEM. QUESTION! -
It looks as if chromium gives up electrons to Tin+2, and aluminum gives up electrons to chronium.
So does that mean aluminum is most active, and tin the most able to reduce?
