The effect of size on the effectiveness of diffusion Aim: To use agar blocks infused with 0.1 Molar sodium hydroxide (NaOH) and phenolphthalein to investigate the relationship between shape and surface area: volume ratio on the effectiveness of diffusion. Hypothesis: That for a cube of agar‚ the time taken for complete colourisation due to diffusion of HCl is directly proportional to the cubes volume. Materials: |A block of agar (10cm x 5cm x 3cm) with 0.1M NaOH and |1x 250mL
