Arrhenius has further shown that the formula can be applied 

 to aqueous solutions of electrolytes and non-electrolytes up to 1.5 

 normal and 10 vol. per cent, solutions respectively, in which 

 the resulting error rarely exceeds one per cent. 



The correctness of the above results in the case of aqueous 

 solutions has since been confirmed by the works of Reyher,^^ 

 Wagner^^ and others.
