Redox Reactions

Question
CBSEENCH11006739
Wired Faculty App

Assign oxidation number of the underlined elements in each of the following species:
NaH bottom enclose straight S straight O subscript 4


Solution
NaH bottom enclose straight S straight O subscript 4
Let the oxidation number of S = x
Writing the oxidation number of each atom at the top of its symbol.
 +1      -1          x - 2
Na        H            SO4 
Sum of the oxidation number of various atoms = 0
                        +1 + 1 + x + 4(-2) = 0
                                       x - 6 = 0
or                                      x = +6
therefore Oxidation number of S in NaHSO4 = +6
