Property on installment in islamabadCut a 1 cm 3 cube of agar. The agar should be made using 0.1 M sodium hydroxide and coloured with phenolphthalein indicator to produce pink-coloured alkaline agar. Place a 1 cm 3 cube of agar into a 0.5 M solution of hydrochloric acid for two minutes. Remove the cube and wash it in water to stop the reaction.

Jones 4 Diffusion Of An Agar Plate And Multiple Different Dyes Essay 1534 Words | 7 Pages. Diffusion “is the ability of a substance to dissipate to equilibrium in a media” (Lange), usually this dispersal of a particle is helped along the way by the use of a concentration gradient. Measure out 1.6 g of agar-agar and 200 ml water. Mix them together with a whisk or fork in a large microwave-safe bowl. Heat the solution in the microwave on high for 30 seconds. Remove to a heat-safe surface using a hot pad or oven mitts, stir, and return to the microwave for 30 seconds.
Agar jelly & Acid experiment study guide by ehutcho13 includes 23 questions covering vocabulary, terms and more. Quizlet flashcards, activities and games help you improve your grades. Agar blocks containing DCPIP are used to represent cells. Ascorbic acid turns DCPIP colourless. Blocks of different SA:V are placed in ascorbic acid and the time taken for the blocks to go completely colourless is recorded. Group results are collated and a graph showing SA:V ratios against time is drawn and a curve of best fit added.
