Hello, to anyone reading this! I'm currently going through a chemistry past paper, and came across a question, asking me to suggest the formula to sodium chlorate (VII). I'm currently at As level chemistry and according to my teachers, we don't do anything related to oxidation powers in such contexts until' next year. So i was a bit off guard for the question. I had a go, and i came out with Na2Cl, as i took the (VII) part to be oxidation power, so i gathered that the compound had a overall charge of +1. So, i got onto the interwebs and searched for the actual formula and the theory to go with it. I found the formula to be NaClO4, and as for for theory, i got as far as the name that has the oxidation power after it, is the alternating number in the compound. I'm just confused with the theory... The compound can oxidise 7 electrons, but when i add up the oxidation numbers across the compound it equals: Na+1 , ClO-1 and O3-6. Added up equalling -6, so the compound has an oxidation of 6? I don't really get where the numbers are coming from. Any help is appreciated, thanks!![]()
