The names of the reactions that take place for copper(II) oxide, CuO in redox reaction: 2CuO + C → 2Cu + CO₂
Reduction
The names of the reactions that take place for carbon dioxide, CO₂ in redox reaction: 2CuO + C → 2Cu + CO₂
Oxidation
Oxidation reaction in terms of gain and loss of hydrogen
Takes place when a reactant loses hydrogen
Reduction reaction in terms of gain and loss of hydrogen
Takes place when a reactant gains hydrogen
Examples of redox reactions involving oxidation and reduction in terms of of Gain and loss of hydrogen
Areaction between hydrogen sulphide, H₂S and chlorine, Cl₂
Oxidised substance in the redox reaction: H₂S(g) + Cl₂ (g) -----> S(s) + 2HCl(g)
Hydrogen sulphide, H₂S
Reduced substance in the redox reaction: H₂S(g) + Cl₂ (g) -----> S(s) + 2HCl(g)
Chlorine, Cl₂
Oxidising agent in the redox reaction: H₂S(g) + Cl₂ (g) -----> S(s) + 2HCl(g)
Chlorine, Cl₂
Reducing agents in the redox reaction: H₂S(g) + Cl₂ (g) -----> S(s) + 2HCl(g)
Hydrogen sulphide, H₂S
The reactions that occur to hydrogen sulphide, H₂S in redox reaction (1): H₂S(g) + Cl₂ (g) -----> S(s) + 2HCl(g)
Hydrogen sulphide, H₂S loses hydrogen
