what is the oxidation number of Ca in CaSO4?

1.	what is the oxidation number of Ca in CaSO4?
Answer» Oxidation no. Of ca is+2<br>Oxidation of O is -2 (4×-2= -8)Oxidation of S is 6 (6×1 = 6)Let oxidation of ca x then Total is zero x+6-8 =0Or x= 2<br>In CaSO4 , oxidation number of Ca is +2<br>+2is the oxidation number of ca in caso4
