Hi, I did a question once and in that Mno4- -> Mno2 but in another question it was Mno4- -> Mn2+ How can these equations defer and is there a way to know what the right side of the half equation is going to be when the left is given?

hi, Is there a way to figure out one side of a redox half equation when the other side is given? ex- Mn04- -> Mn2+

:confused:

totally stuck! hey guys and girls, I'm having some serious problems with this redox reaction titration thing i just did! Basically i titrated a sodium thiosulphate solution with potasium iodate(v), sulphuric acid, potassium iodide and some starch. I've worked out the molarity of my sodium...

This is the 2nd problem on a HW sheet I have. I don't have any particular problems with it but I'm just making sure I'm doing these right: Complete (add H20, H+ or OH- as appropriate) and balance the following equations. Show all half reactions. a. NO_3^- + Ag \rightarrow Ag^+ + NO_2...

Hi ppl. I'm asked a question: Iron filings are added to a solution containing the ions Cu2+, Fe2+, Fe3+, H30+ and Zn2+. Deduce what reactions occur from the standard electrode potentials. Is this simply asking me which will change Fe2+ to Fe3+ and vice-versa by reduction or oxidation do you...

Hello, Anyone know something about Molybdenum(V) ions? 1n our university, we instruct an experiment to students, in which ammonium molybdate (\displaystyle (NH_4)_2MoO_4) is reacted with tin chloride with hydrochloric acid. A redox reaction occurs, to my knowledge it should be like that...

Balance in basic (check my work) NO + MnO4- ------ NO3- + MnO2 4OH- + 4H+ + NO ---- NO3- + 2H2O + 4OH- 4OH- + 4H+ + MnO4- --- MnO2 + 2H2O + 4OH- Balanced with 5 e- on each side 2H2O + NO + MnO4- ----- NO3- + MnO2 + 8OH- Thanks Nautica

Check this Balance in an acidic solution Fe2+ + MnO4- ----- Fe3+ + Mn2+ (Fe2+ ---- Fe3+ + 1e-) x 7 7e- + 8H+ + MnO4- ----- Mn + 4H2O 8H+ + 7Fe2+ + MnO4- ----- 7Fe3+ + Mn + 4H2O Thanks Nautica

Hi I got the following redox-process: IO_3^{-} (aq) + HSO_3^{-}(aq) \rightarrow I_2(aq) + SO_4^{2-}(aq) How do I balance it? Any hits will be apriciated :) Sincerely Fred

KBrO2 + KI + HBr ---> KBr + I2 + H2O eq1 KBrO2 ---> KBr 4e- + 4H+ +KBrO2 ---> KBr + 2H2O eq2 2KI ---> I2 + 2K+ + 2e- 4KI ---> 2I2 + 4K+ + 4e- eq3 HBr ---> KBr K+ + HBr ---> KBr + H+ since the charges in eq3 are +1=+1 you don't have to multiply this equation by 4 do you...
