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 thiosulphate solution is 1.54 but i have no idea how to get the molarity of the potassium iodate(v)!! we've been given these equations: IO3- + 6H+ + 5I- = 3I2 + 3H2O I2 + 2S2O3 2- = 2I- + S4O6 2- (sorry about the equals instead of arrows and the lack of super/subscript!!) but I have no idea what to do with them!! my teachers seem to have missed something vital when explaining all this to us and i really need some help!! thanks in advance!
