Question

what is redox reaction? Explain .​

Answer 1

Redox reactions involve electron transfers; if one species gains electrons, another species (or more than one species) must lose electrons. For example, the redox reaction in which zinc displaces copper in an aqueous solution of copper sulfate:

CuSO4(aq) + Zn(s) → ZnSO4(aq) + Cu(s)

In terms of electrons:

Cu2+(aq) + 2e- → Cu(s)

Reduction of Cu2+(aq)

and

Zn(s) → Zn2+(aq) + 2e-

Oxidation of Zn(s)

These spontaneous reactions (ΔG° for the reaction is -212.6 kJ mol-1) would take place directly between the species if zinc metal were added to a vessel containing copper sulfate solution, releasing heat.

Answer 2

Answer:

redox is a type of chemical reaction in which the oxidation states of atoms are changed.
