Gravimetric Analysis and Theoretical Yield
In a gravimetric analysis experiment, excess BaCl₂ is added to a solution containing sulfate ions, precipitating BaSO₄. The mass of the collected precipitate is lower than the theoretical yield. Which of the following best accounts for this observation?
A
Overlooked potential contamination in the sample
B
Neglected the solubility of BaSO4 in the solution
C
Incorrectly calculated the stoichiometry of the reaction
D
Failed to account for the purity of BaCl2
