Concentration Gradients Experiment 1. For each of the bags‚ identify whether the solution inside was hypertonic‚ hypotonic or isotonic in comparison to the beaker solution it was placed in. Bag #1’s solution was hypotonic compared to the solution of beaker #2. Bag #2’s solution was also hypotonic compared to the solution of beaker #2. Bag #3’s solution was isotonic compared to the solution of beaker #2 and Bag #4’s solution was hypertonic compared to the solution of beaker #1. 2. Which bag

Abstract An experiment is conducted to prepare soap and thus‚ to compare the properties of the prepared soap and synthetic detergents which are precipitation‚ emulsification and cleaning abilities. It can be concluded that soap has the properties if emulsifying oil whereas detergent has not. The abilities of forming precipitates can be seen clearly in soap solution whereas detergent forms no precipitates at all. The experiment is completed and successfully conducted. Introduction
