Question
Chapter 19, Problem 99A
Interpretation Introduction
Interpretation : The accuracy of the statement is to be evaluated.
Concept Introduction : An indicator is a chemical substance that changes color when an acid or base is present.
Expert Solution
Answer to Problem 99A
The statement is not accurate since indicator changes its color according to the pH.
Explanation of Solution
An indicator is a chemical substance that changes color when an acid or base is present.
The titration's end point occurs when the indicator's color changes.
The indicator changes its color depending on the pH of the solution.
They are not precise since they keep changing according to the pH.
Methyl red changes color when exposed to acid.
Interpretation Introduction
Interpretation : The accuracy of the statement is to be evaluated.
Concept Introduction : Acids are used to produce hydrogen ions by ionization. Bases are used to produce hydroxide ions by ionization.
Expert Solution
Answer to Problem 99A
The statement is not accurate since ammonia is a base according to Bronsted Lowry’s theory.
Explanation of Solution
Acids, according to Arrhenius, are substances that contain hydrogen and ionize to produce hydrogen ions
Bases are substances that ionize in aqueous solutions to produce hydroxide ions
The statement is not accurate.
Ammonia is not a base according to Arrhenius’s definition as it does not dissociate to give hydroxide ions.
Ammonia is a base according to Bronsted Lowry’s theory.
Interpretation Introduction
Interpretation : The accuracy of the statement is to be evaluated.
Concept Introduction : Acids are used to produce hydrogen ions by ionization. Bases are used to produce hydroxide ions by ionization.
Expert Solution
Answer to Problem 99A
The statement is not accurate since concentration and strength are two different terms.
Explanation of Solution
The strength of the solution deals with the dissociative nature of the acid or base in the solution.
The concentration of the solution deals with the amount of acid or base present.
The strength is entirely different from the concentration of the solution.
So, they are not related to each other.
The statement is not accurate.
