Fractional precipitation is a technique used to separate two or more ions from a solution based on their different solubilities in water. This method is commonly used to purify substances and to separate ions that are present in small concentrations.
Answer: Ba2+ will precipitate because the concentration of SO42- is greater than 5.5 x 10^-4 M.
Answer: The molar ratio of Ba2+ to Ca2+ in the precipitate is 1:0, because only Ba2+ precipitates.
Answer: 1.1 x 10^-5 M
Answer: 2.5 x 10^-2 M
