Question

If you add HCl into the flask and record the volume, would adding water affect your titration results?

a) Yes, it would dilute the solution
b) No, it would enhance accuracy
c) Yes, it would speed up the reaction
d) No, it would make the solution more concentrated

Answer 1

Adding water to a flask containing HCl during a titration would dilute the solution and potentially lead to inaccurate titration results, because it alters the stoichiometry of the reaction.

Step-by-step explanation:

When HCl (hydrochloric acid) is added into a flask during a titration and you record the volume of acid used, adding water to this mixture would affect your titration results. The correct answer is (a) Yes, it would dilute the solution. Adding water to the acid in the flask would result in a decrease in the solution's concentration. This means that the titrant (the substance being added to the solution to determine its concentration) would have to react with more solvent (water), and consequently, more titrant may be required to achieve the endpoint of the titration. In short, dilution would affect the overall stoichiometry of the titration and could lead to inaccurate results.
