Will there be a reaction between ammonium hydroxide and ammonium chloride?
this reaction will not occur because you will end up with the same substances ammonium hydroxide and ammonium chloride so it is useless to try. this equation will not apply for all salt and alkali reaction. some will have place some will not depending on what substances you have for example table salt(NaCl) will not react with sodium hydroxide but ti will react with potassium hydroxide it all depends in the substance reactivity.
