Titration

What should you do first when setting up the buret?

• Fill it with the titrant to the top

• Rinse it with distilled water only

• Rinse it with a small amount of the titrant solution

• Use it immediately without rinsing

Where should the buret volume be read from?

• The bottom of the meniscus

• The top of the meniscus

• Anywhere below the 0 mL line

• The side closest to the light source

What should be done with the waste after a titration?

• Pour it down the sink directly

• Store it in a waste beaker or liquid waste container

• Pour it into the NaOH solution

• Leave it in the flask for the next experiment

Why is a white background placed under the flask during titration?

• To make the solution color change easier to see

• To keep the flask warm

• To balance the buret stand

• To absorb any spilled solution

How should you handle the pipet before using it for titration?

• Rinse it with distilled water only

• Rinse it with the solution it will be measuring

• Fill it with any solution on hand

• Use it without rinsing

What is the purpose of swirling the flask during titration?

• To keep the solution cool

• To evenly mix the titrant with the solution being titrated

• To make the indicator dissolve faster

• To prevent spills

Why should half-drops be used when close to the endpoint?

• To reduce the concentration of the solution

• To avoid overshooting the endpoint

• To make the color change more vibrant

• To reduce the volume of the titrant

Why is it important to achieve consistent titration values?

• To reduce chemical waste

• To confirm the accuracy and precision of results

• To make the experiment shorter

• To reach the endpoint faster

How do you determine the volume of NaOH used in the titration?

• Subtract the initial buret reading from the final reading

• Add the initial buret reading to the final reading

• Divide the final buret reading by the initial reading

• Multiply the final buret reading by the initial reading

How would incomplete rinsing of the pipet with HCl affect results?

• It would not affect the titration

• It would result in a lower NaOH concentration measurement

• It would result in a higher NaOH concentration measurement

• It would dilute the NaOH solution
