    Is Iodine Acting as an Indicator in Equilibrium Reactions with NaOH and H2SO4?

    um, no i don't really know much about hypochlorites...:( do you mean in this case something like IOH being formed?? so then the equation could be: 2I2(l) + 2NaOH(aq) ---> 2NaI(aq) + 2IOH(aq) 2NaI(aq) + 2IOH(aq) + H2SO4(aq) ---> Na2SO4(aq) + 2H2O(l) + 2I2(l) ? oh and i don't really...

    Is Iodine Acting as an Indicator in Equilibrium Reactions with NaOH and H2SO4?

    Homework Statement this question is contained within the equilibruim area of study. in a practical activity, we were supposed to 1/3 fill a vessel with iodine, and then add NaOH(aq) - when this was done, the yellowy colour of the iodine completely diappeared. we then added the same...

    Complex numbers - describe geometrically

    ahhhh okay; thanks! but I'm still not sure what I should present as a solution. Does 'describe geometrically' mean in terms of equations or words? :D

    Complex numbers - describe geometrically

    Hi! I was just wondering if anyone would be able to help me with a question I received recently as complex numbers homework and didn't quite understand. There was an equation given in complex form ie. something along the lines of |z-2|=|zconjugate=2| (I cannot remember this exactly now...
