How many grams of silver chromate will precipitate when 150 mL of 0.500 M silver nitrate are added to 100 mL of 0.400 M potassium chromate?
WE need (i) a stoichiometric equation........and should get over
Silver chromate is EXCEPTIONALLY insoluble, and will deposit with alacrity as a brick-red precipitate.
And we need equivalent quantities of silver ion and chromate ion.
Clearly, there is EXCESS chromate ion, MORE than 1/2 equiv. And thus all the silver ion will precipitate as silver chromate.
Given the stoichiometry,
