Question

The effect of the burette delivering less volume than the recorded volume of Zn^2+ solution used in titration on the following aspects:

a.) Number of moles of zinc ion determined:

The number of moles of zinc ion determined will be lower than expected because the delivered volume was less than recorded, leading to an underestimation of the zinc ion concentration.
The number of moles of zinc ion determined will remain unaffected since the volume discrepancy does not impact the concentration of the Zn^2+ solution.
The number of moles of zinc ion determined will be higher than expected because the delivered volume was less than recorded, leading to an overestimation of the zinc ion concentration.
The number of moles of zinc ion determined cannot be predicted without additional information.
b.) Number of moles of chloride ion determined:

The number of moles of chloride ion determined will be lower than expected because the delivered volume was less than recorded, leading to an underestimation of the chloride ion concentration.
The number of moles of chloride ion determined will remain unaffected since the volume discrepancy does not impact the concentration of the Cl^- solution.
The number of moles of chloride ion determined will be higher than expected because the delivered volume was less than recorded, leading to an overestimation of the chloride ion concentration.
The number of moles of chloride ion determined cannot be predicted without additional information.
c.) Empirical formula obtained from the experiment:

The empirical formula obtained from the experiment will remain unchanged as the molar ratios between zinc and chloride ions are not affected by the volume discrepancy.
The empirical formula obtained from the experiment will indicate a higher ratio of chloride ions to zinc ions due to the underestimation of zinc ion moles.
The empirical formula obtained from the experiment will indicate a lower ratio of chloride ions to zinc ions due to the underestimation of zinc ion moles.
The empirical formula obtained from the experiment cannot be predicted without additional information.
Keep in mind that the specific impact on results would depend on the extent of the volume discrepancy and the stoichiometry of the chemical reaction involved in the titration.

Answer 1

The effect of the burette delivering less volume than the recorded volume of Zn^2+ solution used in titration can lead to an underestimation of the zinc ion concentration, but will not affect the concentration of the chloride ion solution or the empirical formula obtained from the experiment.

Step-by-step explanation:

The effect of the burette delivering less volume than the recorded volume of Zn2+ solution used in titration can have different impacts on various aspects.

a.) Number of moles of zinc ion determined: The number of moles of zinc ion determined will be lower than expected because the delivered volume was less than recorded, leading to an underestimation of the zinc ion concentration.

b.) Number of moles of chloride ion determined: The number of moles of chloride ion determined will remain unaffected since the volume discrepancy does not impact the concentration of the Cl- solution.

c.) Empirical formula obtained from the experiment: The empirical formula obtained from the experiment will remain unchanged as the molar ratios between zinc and chloride ions are not affected by the volume discrepancy.
