(a) Write the net ionic equation for the reaction of aqueous iron (II) ion reacting with H2O2 in acidic medium. (b) If hydroxide ion is formed, the OH- may react with some of the Fe3+ to produce an insoluble hydroxide. Will the percent yield of the iron (III) compound containing a complex ion be affected by the formation of the insoluble hydroxide? (c) Write the balanced net ionic equation for the formtion of the insoluble hydroxide.
A solution contains 2.40×10-2 M nickel(II) nitrate and 2.40×10-2 M iron(II) acetate. Solid sodium hydroxide is added slowly to this mixture.

A student is given an unknown aqueous solution that contains either the divalent ion or trivalent ion of a certain metal (that is, the solution either contains metal(II) ions or metal(III) ions of the same metal). The student was also given a dilute solution of potassium permanganate which had a vivid purple color. Which of the following might be an appropriate way to ascertain which unknown solution the student was given? Addition of the permanganate solution to the unknown solution...
