oxidation states (6K.1)

Postby dtolentino1E » Sun Feb 16, 2020 2:20 pm

how do i know the oxidation states of elements in compounds?

for example, in 6K.1, it says that C is oxidized from -2 to 1- in C2H5OH --> C2H4O

You would calculate it using the known oxidation states of elements. For example, O is typically -2, C is typically +4, etc. You can use this to calculate this by equating it to the total charge.

Also, the oxidation states should add up to the total charge of the molecule. In the equation you have, both molecules have a total charge of zero so all the oxidation states of each element should add up to zero. If the molecule has a negative or positive charge, then it should add up to that number.
