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

If a certain battery supplies 1.0×108 electrons per second to the negative terminal and the battery contains 7.00 moles of electrolytic solution (which means the solution contains 7.00 moles of hso4), what fraction of the solution undergoes a chemical reaction each second

In which environment would primary succession occur? a forest with a few remaining trees after a recent wildfire an area of exposed rock after a glacier melts away beach that is exposed to the air at low tide an abandoned baseball field in a small town

Salicylic acid is a very important acid. it is used to synthesize the aspirin by treating with acetic anhydride. a 0.2015-g sample of salicylic acid was dissolved in a 100.00-ml volumetric flask, and the solution was diluted to the mark. a 10-ml aliquot of this solution was titrated with standard naoh (0.01130 + 0.2% n) to a phenolphthalein faint pink color end point at 19.81 ml. (a) (calculate the normality of the salicylic acid solution used in the titration. (b) assuming the salicylic acid is pure, what is the equivalent weight of the salicylic acid? practice problems for the final exam (continued) (c) (calculate the inherent error in the determination of the equivalent weight you calculated in part (b). use the following absolute errors in the equipment /glassware when calculating the inherent error. 5.00-ml pipet: + 0.02 ml 100-ml volumetric flask: + 0.08 ml analytical balance: + 0.2 mg 25-ml buret: + 0.03 ml
