Question

oxidation no of K2CrO4

With explaination ​

Answer 1

Answer:

+6

Explanation:

oxidation number of potassium is +1 therefore for k2 it is 2+

oxidation number of chromium be x

oxidation number of oxygen is -2 therefore for o4 it is -8

since there is no charge on the whole molecule

+2 + x -8=0

x-6=0

x=+6

therefore the oxidation number of chromium is +6 -in k2cro4
