Measures the temperature of a solution
2. What types of titrations are commonly used in the pharmaceutical industry?
Acid-base, redox, and complexometric titrations
Precipitation and conductometric titrations
Gravimetric and volumetric titrations
3. How would you handle discrepancies in titration results?
Change the titrant
Double-check calculations and equipment calibration
Ignore the discrepancies
4. What is the principle of titration?
Measure the pH of a solution
Determine the boiling point of a solution
Determine the unknown concentration of a solution by reacting it with a standard solution
5. What is the role of an indicator in titration?
Measures the temperature of the solution

Determines the volume of the titrant
6. How do you calculate the concentration of an unknown solution from titration data?
By measuring the pH of the solution
By determining the boiling point of the solution
Using the formula: Concentration = Moles of titrant × Titrant’s volume / Volume of unknown solution
7. What is the difference between the endpoint and equivalence point in titration?
Equivalence point is when the solution changes color; endpoint is when the solution reaches pH 7
Equivalence point is when moles of acid equal moles of base; endpoint is where the indicator changes color
Equivalence point is when the solution reaches boiling point; endpoint is when the solution reaches freezing point
