Sodium hydroxide is added to a solution that contains 0.049 MA13+ and 0.011 M Mg2+. The concentration of the first ion to precipitate (either A13+ or Mg2+) decreases as its precipitate forms. Which cation precipitates out first and what is the concentration left of this ion when the second ion begins to precipitate ? Select the correct answer. cross out Select one: O A. Mg2+ precipitates out first and there is still a high percentage of Mg2+ left in solution...
