Homework Answers
Oxidation :
Oxidation is the loss of electrons during a reaction by a molecule, atom or ion.
Oxidation occurs when the oxidation state of a molecule, atom or ion is increased
Reduction :
Reduction is the transfer of electrons between species in a chemical reaction where there is a process of gaining electrons or a decrease in the oxidation state by an element
Answers
a) B is best oxidizing agent because it has tendency to accept electrons and its energy is less than A.
b) C is the best reducing agent as it has more electrons it can donate electrons and get reduced by oxidizing other species.
c) No A is not able to oxidize B , because B is comparably stable than A and it cannot donate electrons to A
d) Yes C can reduce A by donationg electrons to A. Because C has more electrons.
