ES2 (Redox reactions + Oxidation states) Flashcards
1
Q
where are electrons placed in half equations for oxidation and reduction?
A
on the right for oxidation, left for reduction
2
Q
what is the oxidising agent?
A
removes electrons so are themselves reduced, they cause something else to be oxidised.
3
Q
what are reducing agents?
A
they cause something else to be reduced and give electrons so are themselves reduced
4
Q
what is the oxidation state of elements?
A
0
5
Q
what do simple ions have oxidation states equal to?
A
the charge on the ion
6
Q
what is the overall oxidation state of a compound equal to?
A
0
