Question

what is oxidation state of C in CuCO3​

Answer 1

Answer:

The oxidation state of any chemically bonded carbon may be assigned by adding -1 for each more electropositive atom (H, Na, Ca, B) and +1 for each more electronegative atom (O, Cl, N, P), and 0 for each carbon atom bonded directly to the carbon of interest. For example: propene: CH3-CH=CH2.
