redox reactions Flashcards
1
Q
oxidation definition
A
the loss of electrons (oxidation state increases)
2
Q
reduction definition
A
the gain of electrons
3
Q
reducing agent definition
A
an electron donor (gains a + charge)
4
Q
oxidising agent definition
A
an electron acceptor (gains a - charge)
5
Q
what are the oxidation states for the 6 elements needed to learn
A
uncombined metals > 0
metals > G1= +1, G2= +2 ext
fluorine > -1
hydrogen > +1
oxygen > +2
chlorine > -1
6
Q
what is a redox reaction
A
oxidation and reduction reactions take place at the same time
7
Q
what is a disproportionation reaction
A
when the same atom is oxidised and reduced in a single reaction
