Ammonia solution - Wikipedia
网页In aqueous solution, ammonia deprotonates a small fraction of the water to give ammonium and hydroxide according to the following equilibrium: NH 3 + H 2 O ⇌ NH + 4 + OH −. In a 1 M ammonia solution, about 0.42% of the ammonia is converted to ammonium, equivalent to pH = 11.63 because [NH +
Ammonium Hydroxide Facts and Formula - ThoughtCo
网页2020年1月4日 · While pure (anhydrous) ammonia is definitely a base (a proton acceptor or substance with a pH greater than 7), people often get confused about whether ammonium hydroxide is also a base. The simple answer is that yes, ammonium hydroxide is also basic. A 1M ammonia solution has a pH of 11.63.
