Ferris & mona used the orp sensor to titrate a ferrous ammonium sulfate solution, (nh4)2fe(so4)2 with kmno4 titrant.
they titrated a 15.00 ml aliquot of the fe+2 solution with 0.0250 m mno4- solution and determined that the equivalence point was at 20.2 ml.

what is the molarity of the fe+2 solution? 5 fe+2(aq) + mno4-(aq) + 8 h+(aq) â 5 fe+3(aq) + mn+2(aq) + 4 h2oselect one: a. 0.168 mb. 0.0928 mc. 0.0337 md. 0.673 m

Solutions of sodium carbonate and silver nitrate react to form solid silver carbonate and a solution of sodium nitrate. a solution containing 3.50 g of sodium carbonate is mixed with one containing 5.00 g of silver nitrate. how many grams of sodium carbonate, silver nitrate, silver carbonate, and sodium nitrate are present after the reaction is complete?
