Oxidation and Reduction (6)

Chemistry

Not quite remember

I easily remember

The reactions that occur to hydrogen sulphide, H₂S in redox reaction (2): H₂S(g) + Cl₂ (g) -----> S(s) + 2HCl(g)

Hydrogen sulphide, H₂S reduces chlorine, Cl₂

The reactions that occur to chlorine, Cl₂ in redox reaction (1): H₂S(g) + Cl₂ (g) -----> S(s) + 2HCl(g)

Chlorine, Cl₂ gains hydrogen

The reactions that occur to chlorine, Cl₂ in redox reaction (2): H₂S(g) + Cl₂ (g) -----> S(s) + 2HCl(g)

Chlorine, Cl₂ oxidises hydrogen sulphide, H₂S

The names of the reactions that take place for hydrogen sulphide, H₂S in redox reaction: H₂S(g) + Cl₂ (g) -----> S(s) + 2HCl(g)

Oxidation (loss of oxygen)

The names of the reactions that take place for chlorine, Cl₂ in redox reaction: H₂S(g) + Cl₂ (g) -----> S(s) + 2HCl(g)

Reduction (gain of hydrogen)

Definition of oxidation reaction in term of electron transfer

Oxidation reaction takes place when a reactant loses electron

Definition of reduction reaction in terms of electron transfer

Reduction reaction takes place when a reactant gains electron

Redox reaction (1)

Not all redox reactions can be explained in terms of loss and gain of oxygen or hydrogen

Redox reaction (2)

Since the discovery of electrons by J.J Thomson in 1897, chemists have started to use the concept of electron transfer in explaining redox reaction

Redox reaction (3)

Primarily, redox reactions can be explained through the concept of electron transfer
