TITRIMETRIC METHODS 



from carbon dioxide, Schmidt-Nielsen (1942) designed a soda lime 

 container that fits on the titration tube as shown in Figure 86. 



It may be observed in Figures 64 and 84 that a titration table 

 is employed which is adjustable both vertically and horizontally. 

 An opal-glass background, illuminated by a small electric bulb, is

provided to facilitate the observation of the color of the solution. 

 The electromagnet placed to the left of the titration table is used 

 for magnetic stirring in the manner described in the section dealing 

 with stirring devices (page 179).
