Academics

A solution is made up by adding 0.839 g of silver(I) nitrate and 1.024 g of lead(II) nitrate to enough water to make 492 mL of solution. Solid sodium chromate, Na₂CrO₄, is added without changing the volume of the solution.

A) which salt will precipitate first, Ag₂CrO₄ or PbCrO₄. (ANSWER - PbCrO₄)

B) What is the concentration of the chromate ion when the first salt starts to precipitate. (ANSWER - 3 x 10^-12)
