Question

Identify the substances that are oxidized and reduced in reaction. cuo+h2-cu+h2o

Answer 1

Substance Oxidised : H2
Substance Reduced : CuO

Answer 2

Hi there !!

CuO + H₂  -----> Cu + H₂O

Oxidation : Gaining of oxygen OR Losing of hydrogen

Reduction : Gaining of Hydrogen OR Losing of Oxygen

Here ,

CuO gets reduced [ it loses oxygen ] and become Cu

H₂ gets oxidized  [ it gains oxygen ] and becomes H₂O

Substance that gets oxidised = H₂
Substance that gets reduced = CuO

Also ,

Oxidising agent = substance that gets reduced = CuO
Reducing agent = substance that gets oxidized = H₂
