The pink agar cubed immersed in Hydrogen chloride (HCl) had a faster process of diffusion than the clear agar cube immersed in Potassium manganate (K2MnO4). The 1cm Clear cube had % of it’s volume diffused. The smaller agar cubes will be more efficient in diffusion because smaller agar cubes have a bigger surface area to volume ratio. Heat the solution in the microwave on high for 30 seconds. Repeat this process until the mixture boils. Remove to a heat-safe surface using a hot pad or oven mitts, stir, and return to the microwave for 30 seconds. Mix them together with a whisk or fork in a large microwave-safe bowl.
