    chemistry practical 32 discussion

    0.048/time taken x 10^6 so it was something like 0.048/25 x 10^6 for the first one . Can anyone please tell me their percentage error? was it 0.25 or 0.5% ?

    for the second experiment we all got from 35 to 45ish . that might explain the rate difference then . anyhow , if enough people got the same result then they'll accept your results . depends on the place you carried the experiment in too , as in its temperature .

    that's tooo high ! in our centre it ranged from 25 to 35 and 35 was the maximum . I personally got 25 . its very concentrated so this would take less time then the 10cm^3 one . What did you get for that then :O
