Question

a student was performing an acid/base titration to determine the molar concentration of a sample of vinegar, using the phenolthalein as an indicator. After dispensing a 10.00 ml sample of vinegar that she was going to titrate, she noticed droplets of her solution clinging to the inside of her pipette. She performed her titration of the sample of vinegar to a light pink end point. How would some of the sample remaining in the pipette affect the calculated value for the molarity of acetic acid in the sample of vinegar? Would it be higher or lower than the true value? Explain why.​

Answer 1

will be lower than the true value.

Step-by-step explanation:

• Since, she lift droplets on the inside of the pipette.

• The volume of the acetic acid needed to be estimated is lower than the actual amount.

• So, it take a lower amount of the titrant.

So, the value of the estimated concentration of acetic acid will be lower than the true value.
