Question
Chapter U6, Problem 1STP
Interpretation Introduction
Interpretation:
An acid and base form of the indicator needs to be identified.
Concept introduction:
According to Bronsted acid- base theory, an acid is a substance which is a proton donor and base is a proton acceptor.
Conjugate base of an acid is formed when an acid loses a proton.
Conjugate acid of a base is formed when a base gains a proton.
Expert Solution & Answer
Answer to Problem 1STP
Among the given options, option (C) is the correct answer.
Explanation of Solution
Reason for correct option:
Since HIn (aq) indicates the acid form of the indicator and this acid on losing a proton becomes In- (aq) which is a conjugate base of the acid HIn (aq).
Hence, HIn (aq) is an acid and In- is the base.
Conclusion
Reasons for incorrect options:
(A) H+ (aq) is the proton and it does not indicate the acid form of the indicator.
(B) In-(aq) is not the acid form of the indicator because it does not have protons to donate.
(D) HIn (aq) is an acid but H+(aq) is not the base form of the indicator.
