Question

What is formal charge of hso4?

Answer 1

hey here your ans Let x be the charge of S atom. As we have to find the formal chargeof S in HSO4 let first identify the others element charge but first assume the charge on S is "x". Hence also, the overall charge onHSO4 is equal to the -1 . +1+X+4(-2) = -1 as the oxygen atoms are 4 that why we multiplycharge of oxygen with 4 here.

Answer 2

-1 is the formal charge on hso4
