What is the purpose of a titration in chemistry?

• To determine the volume of a solution

• To determine the concentration of a solution

• To identify the color of a solution

• To measure the temperature of a solution

What is the purpose of rinsing the pipette with distilled water before use?

• To remove any unwanted chemicals

• To increase the accuracy of the measurement

• To clean the pipette

• To dilute the solution

Why is it important to view the meniscus at eye level when using the pipette?

• To avoid bubbles in the solution

• To ensure accurate measurement of the volume

• To prevent spillage of the solution

• To speed up the process of filling the pipette

What is the purpose of using an indicator in an acid-base titration?

• To measure the volume of the solution
