Question

please read carefully no one has gotten it right yet

Choose all of the statements from below which are true about oxidation and reduction. Oxidation and reduction are opposite processes with respect to bookkeeping electrons. Oxidation is what happens when an element in a substance increases its oxidation number. Electrons appear on the left side of an oxidation half reaction. An oxidant is an oxidizing agent, which becomes oxidized during the course of a redox reaction. Reduction is what happens when an element in a substance loses electrons. Electrons appear on the left side of a reduction half reaction, A reductant is an reducing agent, which becomes oxidized during the course of a redox reaction.

Answer 1

First statement: TRUE

Reason: Oxidation is loss of electron(s) while reduction is gain of electron(s). So, they are opposite processes.

Second statement: TRUE

Reason: During oxidation electron is lost from the element and so, the oxidation number of the element increases.

Third statement: FALSE

Oxidation occurs with the lost of electrons. So, in an oxidation half cell electron is lost from the species and is given as product at the right side of the equation.

Fourth statement: FALSE

Reason: An oxidant is an oxidaizing agent which oxidizes others but itself is reduced during the process.

Fifth statement: FALSE

Reason: Reduction happens when an element gains of electron.

Sixth statement: TRUE

Reason: Reduction means gain of electron(s). So, in a reduction half cell it is appeared at the left side of the equation.

Seventh statement: TRUE

Reason: A reductant is a reducing agent that reduces others and itself is oxidized during the process.
