formed which in the main keep the properties of both 

 bases, but are weaker. Also another explanation could

 tralise the bases, resulting in the formation of saltlike 

 combinations which still were highly hydrolysed, espe- 

 cially in the case of ammonia. These interpretations do 

 not after all differ very much from each other and lead 

 in the main to the same conclusions.
