Class 12 Chemistry - Chapter The p-Block Elements NCERT Solutions | What are the oxidation states of phospho
What are the oxidation states of phosphorus in the following:
(i) H3PO3
(ii) PCl3
(iii) Ca3P2
(iv) Na3PO4
(v) POF3?
Let the oxidation state of p be x.
(i) H3PO3
3 + x + 3(-2) = 0
3 + x - 6 = 0
x - 3 = 0
x = 3
(ii) PCl3
x + 3(-1) = 0
x - 3 = 0
x = 3
(iii) Ca3P2
3(+2) + 2(x) = 0
6 + 2x = 0
2x = -6
x = -6 / 2
x = -3
(iv) Na3PO4
3(+1) + x + 4(-2) = 0
3 + x - 8 = 0
x - 5 = 0
x = 5
(v) POF3 :
x + (-2) + 3(-1) = 0
x - 2 - 3 = 0
x - 5 = 0
x = 5
