You are given a pH meter and a series of solutions (solutions A, B and C). When you measured pH, the results were as follows: pH of solution A= 5.0; p...

Station 1. You have run an experiment studying the effects of the molecular weight of a compound on the rate of diffusion in agar. Compound X has a molecular weight of 25.3 g/mol and compound Y has a molecular mass of 156.2 g/mol. On two separate agar plates, 0.1 g of each substance were transferred and allowed to diffuse for 2 hours. The results below were obtained. Use this information about this situation to answer the following three questions. 1. Question: (CO 1) What was the independent v...
