In a titration for the determination of the chloride ion, a solution of 0.1M agno3 is used against a solution, the volume of which is 100ml. At the completion of the titration, the residual concentrations of silver and chloride ions are equal and the total volume is now 125ml. What additional volume of the silver nitrate solution is needed to effect the precipitation of silver chromate (Ag2CrO4) if the molar concentration of the chromate ion is 1x10^-4.
ksp of AgCl- 1.6x10^-10
Ksp of Ag2CrO4- 9x10^-12
I actually have no idea how to do this question. Please at least give me a starting point.
im not too sure whether this is included in HSC or not. but I am currently studying in ACT and this questions has been giving me ultra head aches…
