Help me! Redox help, product predictions I have a lab that we have to get a perfect score on to pass the class, and I'm so overwhelmed and confused right now I could really use some major help. Basically we were given the names of 9 mixes, and we have to predict whether or not they will have a ppt, and if not then we have to move onto redox, see who wants electrons, who's losing them, and then write the half reactions, balance, and then find the overall Eo(volts). So... the main ones I have trouble with are (and what I have started): Magnesium nitrate and Sodium Sulfate MnNO3 + Na2SO4 --> NaNO3 + MnSO4 ?? Potassium permanganate and 1.0 molar HCl KMnO4 + 2HCl --> Cl2 + K + MnO4 + 2H ?? Potassium iodide and iron III chloride and 1 ml of petroleum ether KI + FeCl3 --> Fe + I + KCl ?? Potassium bromide and iron III chloride and 1 ml of petroleum ether KBr + FeCl3 --> Fe + Br + KCl ?? and Iron II sulfate (acidified with 3 drops of 6 molar sulfuric acid) and .01 molar potassium permanganate FeSO4 + KMnO4 --> i think this neutralizes.. but i dont know I am so swamped with homework, it would be extremely appreicated if someone could even point me in the right direction, thank you!
