Question

find out the oxidation number for the following under line atom (1) pH3​

Answer 1

Answer:

Let x be the oxidation number of P in phosphine PH3.

Since, the overall charge on the complex is 0, the sum of oxidation states of all elements in it should be equal to 0.

x+3(+1)=0

x=+3.

Similarly,

b) Let x be the oxidation number of S in sulphur dioxide SO2.

x+2(−2)=0

x=+4.

c) Let x be the oxidation number of N in nitric acid HNO3.

1+x+3(−2)=0

x=+5.

Let x be the oxidation number of P in phosphoric acid H3PO4.

3(+1)+x+4(+1)=0

x=+5.
