1) A solution contains 5.72Ã10-3 M manganese(II) nitrate and 6.51Ã10-3 M lead acetate. Solid ammonium carbonate is added slowly to this mixture. What is the concentration of lead ion when manganese(II) ion begins to precipitate? [Pb2+] ____= M
2) A solution contains 9.10Ã10-3 M potassium hydroxide and 1.41Ã10-2 M potassium cyanide.
Solid zinc acetate is added slowly to this mixture.
What is the concentration of hydroxide ion when cyanide ion begins to precipitate?
[hydroxide] = ___M
*** I'm stuck on both, please help***
