Question

in oxidation reduction change in ______ of reacting element takes place.
(a) volume
(b) pH
(c) Absorbance
(d) valency​

Answer 1

Answer:

valency is the correct answer

Answer 2

Answer:

In the oxidation-reduction change in the valency of reacting elements takes place.

Explanation:

• Oxidation is the process when the loss of one or more electrons takes place from an element.
• In contrast, reduction is defined as the process in which the gain of one or more electrons takes place by an element.

• This loss or gain of one or more electrons by an element is called its valency.

Hence, in the oxidation-reduction change in the valency of reacting elements takes place.
