Oxidation state

Postby Phi Phi Do 2E » Sat Feb 24, 2018 9:29 pm

To calculate oxidation state in half reactions. Do we have to multiply the charges by the coefficient to find the total oxidation state?

Yes, you should take into account the coefficients when determining oxidation states.

Yes, even if there's multiple of the same molecule, their charges add up.

Yes. Two molecules of a +2 molecule would have a total +4 effect, so you would need to evaluate the amount of negative charge needed accordingly.

Yes, you have to multiply the coefficient with the charges because the charge is only for one atom/molecule so if you have multiple of the same molecules/atom then you have to multiply the charge by the coefficient.
