Results. 
Fig. i shows the curves obtained for aluminium chloride (I), barium 
chloride (II), potassium chloride (III), barium nitrate (IV), and potassium 
nitrate (V). 
In each case the concentration C, expressed in gram-mols per litre, is 
plotted horizontally, while the time T needed to produce the change is 
plotted vertically.
