For example, ammonia acts as a base when it reacts with hydrochloric acid to form ammonium chloride.
例如，氨在与盐酸反应生氯充当碱。
That's the ammonium chloride powder forming.
那氯粉末形程。
Fun fact: ammonia and hydrochloric acid react together readily to form a solid -- ammonium chloride.
趣味知识：氨和盐酸很容易反应生固体——氯。
Because the ammonium chloride is a solid at room temperature, it forms a superfine white powder where the two gases meet in the tubes, so we'll be able to tell exactly how far each gas traveled before they met.
因为氯在室温下固体，所以当两种气体在管中相遇， 会形极细白色粉末， 这样我们就能准确地知道每种气体在相遇前走了多远。
