Question 11: Ion (+2) below domestic susceptible to oxidation to ions (+3) most (at the same conditions)?
A) Mn 2 + b) Co2 + c) Fe 2+ d) Cr2 +
Explain
elements from Cr to Co in 3d array. As a rule in the cycle from left to right, the high positive oxidation resistance gradually, so as time goes on more and reliable +2 oxidation number, more complex hexaaqua of Cr (+2) Balance configuration d3d1 1e than saturated configuration d3 sale should be strongly reducing.
