請問,有冇辦法於日常用品中取得氫氣?

electrolysis of water / dilute sodium chloride solution (dilute salt solution)
put 2 carbon electrodes into water and conduct electricity to the electrodes
hydrogen gas will be formed at negative electrode (cathode)
you can use inverted tubes to collect the gases
(hydrogen at negative electrode and oxygen at positive electrode)

also
Hong Kong town gas contain hydrogen as the main constituent
you can collect hydrogen from it
but it is very dangerous

lastly
you can buy compressed hydrogen

唔係日常用品都可以的,但要一種金屬元素-鈀,符號Pd,能不斷吸取大量氫氣,至於於日常用品中取得氫氣是沒可能的!

無
一定要刻意整出黎
