Surface Area to Volume Ratio Simulation Experiment. The comparison between surface area : volume ratio and time taken for agar blocks to decolourise.
The first 200 words of this essay...
Table 1.0 Observations on before, during and after experiment.
Agar blocks are dark brown in colour.
Agar blocks slowly start to decolourise after putting in the dilute hydrochloric. The centre of the block is the last to decolourise.
The agar blocks are light yellow.
The smaller blocks appear to decolourise faster than the bigger blocks.
Smallest block decolourise completely first. Biggest block decolourise lasts.
Decolouration is slower as it approaches the centre.
Table 1.1: Surface area, volume, and ratio of surface area to volume of the agar blocks.
