(1a) A solution contains 1.33×102 M ammonium sulfide and 6.92×10³ M potassium fluoride. Solid calcium nitrate is added slowly to this mixture. A. What is the formula of the substance that precipitates first? formula = B. What is the concentration of calcium ion when this precipitation first begins? [Ca²+] = M (1b) A solution contains 1.37×102 M ammonium carbonate and 1.20×10M sodium hydroxide. Solid nickel(II) acetate is added slowly to this mixture. A. What is the formula of the substance that precipitates first? formula = B. What is the concentration of nickel ion when this precipitation first begins? [Ni²+] = M
