Question

You discovered that the burette you used for titration delivered less volume than the recorded volume of Zn2+ solution. How would the number of moles of zinc ion determined be affected?

Answer 1

If the burette used for titration delivered less volume than the recorded volume of Zn2+ solution, the number of moles of zinc ion determined would be affected. The calculated number of moles would be lower than the actual amount present in the solution.

Step-by-step explanation:

If the burette used for titration delivered less volume than the recorded volume of Zn2+ solution, the number of moles of zinc ion determined would be affected.

In a titration, the number of moles of a substance is determined by the concentration and volume of the solution used. If the burette delivered less volume, the calculated number of moles of zinc ion would be lower than the actual amount present in the solution.

For example, if the recorded volume of Zn2+ solution was 50 mL, but the burette only delivered 40 mL, the calculated number of moles of zinc ion would be based on the lower volume, resulting in an underestimation of the actual moles of zinc ion.
