EXAMPLES:
What is O.N. of S in H2SO4 ?
• H has an O.N. of
• O has an O.N. of
• 2 * O.N. (H) + 4 * O.N. (O) =
- overall charge of molecule is 0
therefore O.N. of S in H2SO4 is :
What is O.N. of N in HNO3 ?
• H has an O.N. of
• O has an O.N. of
• O.N. (H) + 3 * O.N. (O) =
- overall charge of molecule is 0,
therefore O.N. of N in HNO3 is :
this shows the nitrate group: “ NO3 “ has a net O.N. of
(and thus a charge) of
THUS the O.N. of Ag in AgNO3 is
