In 1950, Chairman Mao Zedong made a speech in support of traditional Chinese medicine (TCM) which was influenced by political necessity. Zedong believed he and the Chinese Communist Party should promote TCM but he did not personally believe in TCM and he did not use it.
Yes. The ammonium ion has a formula of NH4+ and has a positive charge so it is a cation.
The ammonium ion is generated when ammonia, a weak base, reacts with BrÃ¸nsted acids (proton donors): The ammonium ion is mildly acidic, reacting with BrÃ¸nsted bases to return to the uncharged ammonia molecule: Thus, treatment of concentrated solutions of ammonium salts with strong base gives ammonia. When ammonia is dissolved in water, a tiny amount of it converts to ammonium ions: The degree to which ammonia forms the ammonium ion depends on the pH of the solution.
