The amount of EDC affects the benzoic acid system and the time it takes for crystallization to occur. Increasing the amount of EDC causes the crystallization to occur and dissapate [sic] faster. For example, 0.25 mL of EDC stock solution was added it took 52 seconds for onset cloudiness to occur. However, when 0.10 mL of EDC solution was added it took 118 seconds for onset cloudiness to occur.
