How Is a Blank Used in Mohr Titration?

[h6872]

Hi... I was wondering exactly how a blank is used for a titration. Is the purpose to simply remove the extra "noise" in the results? If so, I guess I would subtract this blank from the calculated volumes of AgNO3 used... right? Please help! Thanks, -heather

Heather, please describe the titration (including how you would use a blank) and its purpose more clearly. Do not assume we know what your experiment is. it sounds like the determination of chloride ion concentration, but that's speculation. We need more detail from you.
