Determine Concentration of Potassium Chromate to Use (Mohr Titration)
Not what you're looking for?
A titration of 0.100 M Cl^- with 0.100 M Ag^+ used an end point where silver chromate gives an orange precipitate. Select the concentration of potassium chromate that must be present so the orange-colored silver chromate precipitate will appear just when 99.5% of the chloride has been precipitated.
Given: Ksp of AgCl = 1.0 x 10^(-10)
Ksp of Ag2CrO4 - 1.1 x 10^(-12)
