Problem 14E

Does a large positive electrode potential indicate a strong oxidizing agent or a strong reducing agent? What about a large negative electrode potential?

Step-by-Step Solution:
Step 1 of 3

Solutions  Use of Van’t Hoff equation to find molecular weights of macromolecule cells o Know mass of the macromolecular sample o Dissolve the sample as ‘B’ in your osmotic pressure apparatus o Measure pi, T (temperature), and known R (gas constant) o Calculate molarity o Calculate molecular weight (measured in Daltons)  Engineering application: o Apply excess pressure to the solute-containing side of the apparatus.  This drives solvent from the solution to the pure solvent  “reverse osmosis”  Colloidal dispersions Phase Primary Secondary Type Example Gas Solvent Solute -------- --------- Gas Gas --------- --------- Gas Liquid Aerosol Fog Gas Soild Aerosol Smoke Liquid Liquid Gas Foam Whipped Cream Liquid Liquid Emulsion Milk Liquid Solid Sol Paint Solid Solid Gas Solid Foam Marshmallow Solid Liquid Solid Emulsion Butter Solid Solid Solid Sol Ruby  Detect colloidal dispersions by using: o Tyndall Effect  Due to the fact that colloid
