Q2. Which of the following is NOT a type of titration?
Solution:
Thermal titration is not a recognized type of titration; the common types include acid-base, redox, and complexometric titrations.
⏱ Time: 0s
Q3. What is the purpose of a back titration?
Solution:
Back titration is used to determine the concentration of a reactant indirectly by reacting it with an excess of titrant and then titrating the excess.

Q4. What is the significance of the equivalence point in titration?
Solution:
The equivalence point is significant because it is the stage in the titration where the amount of titrant added is stoichiometrically equivalent to the amount of analyte present.

Q5. In a titration, what is the endpoint?
Solution:
The endpoint of a titration is the point at which the reaction between the titrant and the analyte is complete, often indicated by a color change.

Q6. What is the primary purpose of a titration?
Solution:
Titration is primarily used to determine the concentration of a solute in a solution by reacting it with a reagent of known concentration.

Q7. Which indicator is commonly used in a strong acid-strong base titration?
Solution:
Phenolphthalein is commonly used as an indicator in strong acid-strong base titrations because it changes color around pH 8.2 to 10.
⏱ Time: 0s
Q8. Which of the following is a common type of titration?
Solution:
Redox titration is a common type of titration that involves the transfer of electrons between the titrant and the analyte.
⏱ Time: 0s
Q9. In a titration curve, what does the steepest slope indicate?
Solution:
The steepest slope in a titration curve indicates the equivalence point, where the amount of titrant added is stoichiometrically equivalent to the analyte.
⏱ Time: 0s
Q10. Which of the following factors can affect the accuracy of a titration?
Solution:
All of the listed factors, including temperature, concentration of the titrant, and choice of indicator, can affect the accuracy of a titration.
