Here's a taster:

Sodium Thiosulphate solution and hydrochloric acid are
mixed in a flask over a paper marked with a cross. The cross
is viewed from above and the time for it to vanish is noted.
This is repeated to find our end values.
My conclusion is that the higher concentration of sodium
thiosulphate used, the higher the rate of reaction. For
example when we used 50cm³ of sodium thiosulphate and
0cm³ of water, the rate of reaction was 0.028, but when we
used 10cm³ of sodium thiosulphate, and 40cm³ of water, the
rate of reaction was 0.004.…read more
