The final oxidation state of the neutral solution was +4. The final oxidation state of the basic solution was +6. 2) MnO 4-+ 8H + + 5e-→ Mn 2+ + 4H 2 O MnO 4-+ 2H 2 O + 3e-→ MnO 2 MnO 4-+ e-→ MnO 4 2-+ 4OH-3) The formula of the basic product precipitated was Mn(OH) 2 . Conclusion The point of this experiment was to show that during acid/base reactions a change in oxidation state can occur and did. This is shown through a series of reactions that test the different reactions that give proof of this fact. This experiment is valid through the use of more than one trial, increasing the chance of an accurate result....
