Redox Reactions – Solutions
1) Assign oxidation numbers to the underlined elements in each of the following species:
a) NaH2PO4 b) NaHSO4 c) H4P2O7 d) K2MnO4 e) CaO2 f) NaBH4 g) H2S2O7
h) KAl(SO4)2.12H2O
Solution
a) +1 +2x -8
NaH2PO4
According to oxidation number (ON) rules, sum of all the atoms in an neutral molecule should be zero.
Then,
1+2+x -8=0
So, x=+5
