Which of the following are true for an acid-base titration?

Question

Which of the following are true for an acid-base titration? (A) Indicators catalyst the acid-base reactions by relasing or accepting H ⊕ ions (B) Indicators do not significantly affect the pH of the solution to which they are added (C) Acid-base reactions do not occur in the absence of indicators (D) Indicators have different colours in dissociated and undissociated forms

Tardigrade Admin · Accepted Answer

a. Wrong statement
b. Correct: Indicator are weak acid or base and are added is small amount. So they do not affect the

p H

of the solution
c. Wrong: They occur even in the absence of indicators
d. Correct: Factual statement

Q. Which of the following are true for an acid-base titration?

Indicators catalyst the acid-base reactions by relasing or accepting $H^{\oplus}$ ions

Indicators do not significantly affect the pH of the solution to which they are added

Acid-base reactions do not occur in the absence of indicators

Indicators have different colours in dissociated and undissociated forms

a. Wrong statement
b. Correct: Indicator are weak acid or base and are added is small amount. So they do not affect the $p H$ of the solution
c. Wrong: They occur even in the absence of indicators
d. Correct: Factual statement
