Do you need to add anything else to the tube before using the new solution?The pH probe/meter uses following equations: Ecell = L + 0.0592 log a1 = L - 0.0592 pH Where L = L1 + EAg/AgCI + Easy= constants L1 = - 0.0592 log a2 a1 = activity of analyte solution a2 = activity of internal solution How will measured pH value be affected vs “real” pH if HCl in pH electrode, became 0.15M instead of 0.1M ? a.impact can not be determined b.measured pH is higher than "real" pH. c.measured pH is lower than "real" pH. d.measured pH is same as "real" pH.With the principles of GFC, which of the following statements is incorrect?a. For small molecules, their elution volume, Ve > VOb. For a very large molecule, its elution volume, Ve = Voc. Blue dextran is used to determine the void volume because it is too large and cannot get into the beads and therefore excluded from the gel.d.
