Procedure 4.6.a Solution Preparation

Wash all glassware with concentrated H2SO4 and plasticware with 3 M HC1. All reagents and water should be of highest purity. 

Just prior to each kinetic run, prepare 10 ml AA plus LiC104 according to Table 4.7. Out-flow solutions must be prepared with twice the desired concentration since 

TABLE 4.7 Initial or Outflow AA-LiC104 Solutions in a Total Final Volume (Vf) 10 ml 

In-Flow Concentrations The final or in-flow concentrations (i.e., after equal mixing of the two reactant solutions) for the reactants are given in Table 4.8. Calculate the ionic strength, /a(m) of the reaction solution using equation (4.16) where c and z are the concentration and charge of the ith ion in solution. (See Chapter 7, experiment 7.4, for a more rigorous consideration and calculation of ionic strength effects.)
