You have two 500.0 ml aqueous solutions. solution a is a solution of a metal nitrate that is 8.246% nitrogen by mass the ionic compound in solution b consists of potassium, chromium, and oxygen; chromium has an oxidation state of +6 and there are two potassiums and 1 chromium in the formula. the masses of the solutes in each solution are the same. when the solutions are added together, a blood-red precipitate forms. after the reaction has gone to completion, you dry the solid and find that it has a mass of 331.8 g. identify the ionic compounds in solution a and solution b. identify the blood-red precipitate. calculate the concentration (molarity) of all ions in the original solutions. calculate the concentration (molarity) of all ions in the final solution.

The molarity of a solute in solution is defined to be the number of moles of solute per liter of solution (1 mole = 6.02 × 1023 molecules). if x is the molarity of a solution of magnesium chloride (mgcl2), and y is the molarity of a solution of ferric chloride (fecl3), the molarity of chloride ion (cl−) in a solution made of equal parts of the solutions of mgcl2 and fecl3 is given by m = x + 1.5y . assume that x has mean 0.125 and standard deviation 0.05, and that y has mean 0.350 and standard deviation 0.10.
