#1
What is titration?A method to determine the concentration of a solution using a standard solution of known concentration.
A method to boil a solution to remove impurities.
A method to measure the volume of a solution using a graduated cylinder.
A method to evaporate a solution to obtain a solid residue.
#2
Which indicator is commonly used in an acid-base titration?Methyl red
Phenolphthalein
Bromothymol blue
Litmus
#3
What is the primary role of a burette in titration?To measure the volume of the titrant added to the analyte solution
To measure the volume of the analyte solution
To hold the indicator solution
To heat the solution during titration
#4
What is the function of a conical flask in titration?To measure the volume of the titrant
To contain the analyte solution
To hold the indicator solution
To mix the titrant and analyte solution
#5
What is the endpoint of a titration?When the solution changes color
When the pH of the solution equals 7
When the titrant is added dropwise
When the titration flask is heated
#6
What is the primary standard in a titration?The solution of unknown concentration
The indicator
The titrant
The solution of known concentration
#7
What is the equivalence point in a titration?The point where the titrant is added dropwise
The point where the indicator changes color
The point where the moles of acid equal the moles of base
The point where the pH of the solution equals 7
#8
Which type of titration is used to determine the concentration of a reducing agent?Acid-base titration
Redox titration
Complexometric titration
Precipitation titration
#9
Which factor can affect the accuracy of a titration?Temperature
Color of the titrant
Size of the titration flask
Density of the indicator
#10
What is the purpose of standardization in titration?To determine the concentration of the analyte solution
To determine the concentration of the titrant solution
To calibrate the burette
To determine the volume of the titrant
#11
What is the purpose of back titration?To determine the concentration of an unknown solution that reacts slowly
To determine the concentration of a weak acid
To determine the concentration of a strong base
To determine the concentration of a primary standard
#12
What does the term 'titration error' refer to?The difference between the actual endpoint and the observed endpoint
The difference between the initial volume and the final volume of the titrant
The difference between the molarity of the titrant and the analyte
The difference between the density of the indicator and the analyte solution
#13
What is the difference between direct and reverse titration?Direct titration starts with an excess of analyte, while reverse titration starts with an excess of titrant.
Direct titration uses a weak acid as an analyte, while reverse titration uses a strong acid.
Direct titration is used for strong acids, while reverse titration is used for weak acids.
Direct titration is faster than reverse titration.
#14
What is the purpose of using a blank titration?To account for impurities in the indicator
To determine the accuracy of the burette
To subtract any background signal from the titration curve
To standardize the titrant
#15
Which indicator is commonly used in a complexometric titration of calcium ions?Methyl red
Phenolphthalein
Eriochrome black T
Bromothymol blue
#16
What is the primary advantage of using a digital burette in titration?It allows for more accurate volume measurements
It eliminates the need for an indicator
It speeds up the titration process
It reduces the risk of titration errors
