Question #c1aeb

1 Answer

the oxidation state of carbon in #K_2CO_3 # is #+4#

Explanation:

let the oxidation state of carbon be #x#
the oxidation states of potassium and oxygen are fixed i.e. the are #+1# and #-2# respectively.
which means we get #2(+1)+x+3(-2)=0# since the net charge is zero.
#rArrx-4=0# #rArrx=+4#
