The element that gains electrons, becomes reduced.
While the one which loses electrons, becomes oxidized.
In this equation,
CH₃OH + Cr₂O₇²⁻---- --> CH₂O + Cr³⁺.
By balancing the equation, we will get:
3CH₃OH + Cr₂O₇²⁻ + 8H⁺ --> 3CH₂O + 2Cr³⁺ + 7H₂O
Here the oxidation state of Cr changes from +6 to +3 that is it is being reduced thus serving as a oxidizing agent while other element retain their charges.
Here Cr₂O₇²⁻ is reduced while CH₃OH is oxidized.
So Cr₂O₇²⁻ serves as a oxidizing agent, while CH₃OH serves as reducing agent .
Answer:
CICUO3
Explanation:
copper 1 chlorate is made up of copper ion and a polyatomic ion of chlorine and oxygen
When magnesium ion doesn't give any characteristics colour with the flame test as electronic transisitons do not give out visible light.
Divide 1.25/3.93 and then multiply by 100 to get the percent. This equals 31.81%
