5. Four dialysis bags (labeled a, b, c, d, and e) filled with solutions of varying concentrations of solutes are placed in separate beakers with DI water. They are periodically weighed to see if they have gained or lost water through their membranes permeable to only water. The data are then graphed. Weight Change (8) Time (min.) a. Using the data shown in the above graph, which line represents change in weight of a dialysis bag that is hypertonic to...

CRITICAL THINKING QUESTIONS 1. A pre-weighed dialysis bag which contained a solution of 10% glucose was placed in a beaker containing a solution of 20% glucose. After one hour, the bag was weighed again a. Calculate the % mass change of this dialysis bag from the following information: • Mass of bag before experiment: 15.39 • Mass of bag after experiment: 12.79 b. Determine the tonicity of the beaker when it is compared to the dialysis bag: 2. facell had...

74 Percent Concentration -The amount of solute dissolved in a fixed amount of solvent is called the concentration of the solution. Concentrations are typically expressed as Mass al.) (% m/m) which is the mass of the solute (g) divided by the mass of the solution [solute+ solvent] (g)x 1000/0; or as Volume ol.) (% v/v ) which is the volume of the solute in a fixed volume of solution (1O0mL of solution) x 1000/0; or less commonly in the laboratory,...

Acid-Base Titration of a Weak Acid with a Strong Base: Determination of K. Introduction: You will be titrating a solution of a weak acid with 0.100 M NaOH, while monitoring the reaction using a pH meter. Weak acids have characteristic acid-ionization constants, K. The purpose of this lab is to use the titration to determine the value of this constant for the weak acid called “benzoic...
