Question:

Tina, the titrating student, did not completely dissolve her antacid tablet prior to beginning the titration and still had some chunks of tablet in her solution at the end of her titration. How would this affect her results (i.e. would the calculated mass of antacid be high, low, or unchanged)? Explain.

    Tina's calculated mass of antacid would be low. This is because not completely dissolving the tablet means there will be unreacted chunks of antacid present in the solution at the end of the titration. These unreacted chunks will not be taken into account when calculating the mass of antacid since they did not participate in the reaction. As a result, the calculated mass of antacid will be lower than the actual mass present in the tablet, leading to an underestimation of the antacid's effectiveness.
