Aqueous solution in both sulfate ion and chromate ion
Posted: Wed Jan 10, 2024 12:54 am
An aqueous solution is 0.10 M in both sulfate ion and chromate ion. Powdered lead nitrate(Ⅱ) is slowly dissolved in the well-stirred solution. (Assume no volume change).
(a) What is the concentration of Pb²⁺ when PbSO₄ first start to precipitate?
(b)What is the concentration of Pb²⁺ when PbCrO₄ first start to precipitate?
(c) Which compound precipitate first?
(d)When the second anion just start to precipitate, what is the molar concentration of the anion that precipitate first?
I am working on all these questions. If any member knows correct answers, may reply those answers.
