Question

Oxidation number of NaHSeO4?


I think Na=1, H=-1, Se=8, O=-2.

Am I right?

Answer 1

Yes your answer appears to be correct.

Answer 2

Yep, unless there is a charge or ion, the sum of the oxidation states must be zero.

Answer 3

Thanks! But I think I noticed a mistake, shouldn't H be +1 making Se=+6?

Answer 4

Hmm yes Na and H would be +1 therefor Se would most likely be +6 sorry for the confusion
