Question

why does permanganate ion react more with iron irons than with oxalate ions

Answer 1

Do you mean iron ions?

Answer 2

The nature of the reactants:

Reactions between simple ions are almost instantaneous; reactions between more complex ions take longer.

An experiment to compare the rate of the reaction between permanganate ions and iron(II) ions in acid solution, and the rate of the reaction permanganate ions and oxalate ions in acid solutions.The permanganate solution is purple and is decolorised quickly in the iron(II) ion solution. A relatively large time interval is required for the same number of permanganate drops to be decolorised in the oxalate ion solution.

Answer 3

wow thanks :) is it the same when heated in a flame, steel wood burns but the steel nail just glows?

Answer 4

This should explain why wood burns.

When you heat an iron nail however, you are supplying it with energy.

Answer 5

wow thanks !

Answer 6

You're welcome

Answer 7

wait I meant steel wool not wood !

Answer 8

Normally we do not think of iron as being flammable, this is because bulk iron doesn't self-sustain its burning like most flammable materials. But the strands of steel wool are thin enough with enough surface area that heat produced is self-sustaining and will continue to burn through if there is enough air present.
