Chemistry practical paper 31 was today. I'm sure we all agree what a piece of "human waste" it was..... Hopefully cambrigde will do some moderations to help us or else we'll all be dead.
according to pohluk, the rate of reaction is affected by the amount of H+ ions. The total volume of the entire solution has to be kept constant. That means the amount of water you add has to decrease because you add more HCl.
And SO3 is in FA3 while SO4 is in FA6. What the hell.... from what joker/batman told me, you have to test with chromate because the SO3 releases SO or something like that and it changes the chromate from orange to green. Wonderful.
and the last page, the cations are Ba2+, Mn2+, NH4+
and i made a careless mistake when calculating the gradient of the graph. i subtracted the the y and x values instead of dividing them. what the hell.......
Anyway, good luck for maths tomorrow.

Rate of reaction should not be affected according to theoretical means. But my results was somewhere like affected and not affected. No real idea how it works.
Screw this paper lar
who cares. this is practical.
it's in excess la.Tat's y not affected la...
