b.
Answer to Problem 32A
Oxidation-reduction reaction.
Explanation of Solution
The oxidation state is defined as the charge(s) that an atom would have when electron(s) were transferred completely from a molecule or ion. (The element being oxidized is the one whose oxidation number increases in the reaction whereas the reduced element is the one whose oxidation number decreases in the reaction.)
The oxidation number of the involved elements in the given reaction is:
In the given reaction, the oxidation state of hydrogen decreases from +1 to 0 and the oxidation state of zinc increases from 0 to +2. Since, hydrogen undergo reduction and zinc undergo oxidation so, the reaction is oxidation-reduction reaction.
