Design an experiment, based on the principles of diffusion and osmosis, that the assistant could use to determine which of the flasks contains each of the four unknown solutions. Include in your answer (a) a description of how you would set up and perform the experiment: (b) the results you would expect from your experiments: and (c) an explanation of those results based on the principles involved. (Be sure to clearly state the principles addressed in your discussion.)
A) My way of arranging this lab, first I would collect the needed materials. Second, create a question to go along with the experiment. Then I put each flask in a tube and tie it. Afterwards, I would place the flasks in separate cups. In that case, make a hypothesis/prediction (flask A is 0.2, flask B is 0.6, flask C is O.8 and flask 0.4). After that, add potassium iodide and wait 30 minutes. Make observations. List errors in the experiment, state if your hypothesis is correct or incorrect.
B) 0.2, 0.4 are weak solutions; therefore they would go through osmosis, going from low to high concentration. 0.6, 0.8 are strong solutions would undergo diffusion, going from high to low concentration.
