The amount of iron (Fe) in a meteorite(陨石) was determined by a redox titration using KMnO4 as the titrant. A 0.4185-g sample was dissolved in acid and the liberated Fe3+ quantitatively reduced to Fe2+ using a reductor column (还原柱). Titrating with 0.02500 M KMnO4 requires 41.27 mL ...
FeSO4 + H2SO4 + KMnO4 ->? since I'll have excess H2SO4. Would this effect my data on the redox titration?! I'm going to thank you guys before hand: THANK YOU A MILLION TIMES!!
In summary, the conversation is about a person needing help with a chemical practical involving redox titration between h2o2 and KMnO4. They are specifically looking for a specimen calculation to determine the concentration of h2o2 and need assistance with converting dm3 to liters. ...
