Concept Introduction:
Bronsted acid-base reaction:
An acid-base reaction according to Bronsted-Lowry definition is a transfer of a proton from one molecule or ion to another.
Lewis acid-base reaction:
A Lewis acid-base reaction is a
The general form of Lewis acid-base reaction is,
Redox reaction:
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An
(d)
Answer to Problem 8I.3E
The reactions (a) and (b) are redox reactions whereas reaction (c) is acid-base reaction.
Explanation of Solution
The reaction (a) is,
In this reaction, the oxidation number of potassium gets reduced thus, it is a redox reaction.
The reaction (b) is,
In this reaction, the bromine is reduced to bromide ion thus, it is a redox reaction.
The reaction (c) is,
Sodium chloride is a base and sulfuric acid is an acid. This is the reaction between an acid and base thus, it is an acid-base reaction.
