#1
What is the primary function of an indicator in a titration?
To provide color change at the endpoint
ExplanationIndicates the completion of reaction.
#2
In a titration, what is the equivalence point?
The point at which the titrant is added in stoichiometrically equivalent amounts to the analyte
ExplanationWhen reactions are balanced.
#3
What is the purpose of standardization in volumetric analysis?
To ensure the accuracy of the titrant concentration
ExplanationConfirms the concentration.
#4
Which type of titration is commonly used for determining the concentration of acids or bases?
Acid-base titration
ExplanationAnalyzes acidic/basic solutions.
#5
In a precipitation titration, what is the endpoint of the reaction?
When a precipitate first forms
ExplanationAppearance of solid.
#6
What is the role of a burette in titration?
To deliver a precise volume of titrant
ExplanationAccurate volume dispensing.
#7
What is the significance of a blank titration in volumetric analysis?
To account for impurities in the titrant or solvent
ExplanationSubtracts background.
#8
What role does a primary standard play in titrations?
To provide a precise concentration of a substance
ExplanationKnown reference.
#9
Why is it important to perform a titration under controlled conditions, such as constant temperature?
To improve precision and accuracy
ExplanationEnhances result reliability.
