Oxidation state

[Phi Phi Do 2E]

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

[Britney Alvey 1B]

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

[Erik Khong 2E]

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

[Yixin Angela Wang 2H]

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.

[Leanne Wong 1H]

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.
