1a A solution contains 1.33x102 M ammonium sulfide and 6.92x10-³ M sodium fluoride. Solid calcium nitrate is added slowly to this mixture. What is the concentration of fluoride ion when sulfide ion begins to precipitate? [fluoride] = 1b A solution contains 1.37x102 M ammonium carbonate and 1.20x10² M sodium hydroxide. Solid nickel(II) acetate is added slowly to this mixture. What is the concentration of hydroxide ion when carbonate ion begins to precipitate? [hydroxide] = M M 1c A solution contains 5.32x10-³ M magnesium acetate and 7.36x10³ M calcium nitrate. Solid potassium fluoride is added slowly to this mixture. What is the concentration of calcium ion when magnesium ion begins to precipitate? IM [Ca²+] =
