Given the redox reaction:
cr3+ + al--> cr + al3+
as the reaction takes place, there is a transfer of
(1) electrons from al to cr3+
(2) electrons from cr3+ to al
(3) protons from al to cr3+
(4) protons from cr3+ to al

(1) electrons from Al to

Explanation: Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

For the given reaction:

The oxidation state of chromium reduces from +3 to 0, it is getting reduced and gains electrons. The oxidation state of aluminium increases from 0 to +3. Thus, it is getting oxidized and it loses electrons. Thus electrons are transferred from to
