一、氢的制取氢气本身是无臭的气体,但我们每次用锌和稀硫酸或稀盐酸作用制取时,总因锌中含有少量的硫化锌,致使取得氢气带有很重的硫化氢臭味,因此许多化学教师每逢制氢时,都是把带臭味的原因解说一下就算完事,我认为这是不够的,我们必须实事求是的真正设法取出无臭的氢,让同学们亲自看见了在学习中才能解除了怀疑。获得纯净氢的办法是把氢通过四个连续不断的盛有碱液或铜盐溶液的
First, the hydrogen production Hydrogen itself is odorless gas, but each time we use zinc and dilute sulfuric acid or dilute hydrochloric acid when the system, the total zinc as a small amount of zinc sulfide, resulting in hydrogen with a heavy vulcanization Hydrogen odor, so many chemical teachers every time the hydrogen is made, explain the reasons for the smell, even if it is done, I think it is not enough, we must seek truth from facts really try to remove the odorless hydrogen, so that students personally I saw in learning can lift the suspicion. The only way to get pure hydrogen is by passing hydrogen through four continuous streams of lye or copper salt
