Part A.4 and Part B. In a hurry to complete the experiment, Anna withdrew two volumes of solution from Part A.2 before the precipitate had settled. As a result, what dilemma might she have encountered in Part B

Anna may have trouble because of inaccurate results or observations.

Explanation:

In chemistry, a precipitate is an insoluble solid that is gotten from a liquid solution. Because Anna withdrew two volumes of solution from Part A.2 before the precipitate had settled she may find it difficult to determine the limiting reactant; that is the chemical element or substance that limits the amount of product made during the chemical reaction because some precipitate was captured with the liquid lying above, which when adding the reagent, will not show the difference between them.
