Chemistry: how to obtain hydrogen at room temperature

An easy way to obtain hydrogen at room temperature. Bits of zinc were put on the bottom of a bottle; an 1:8 sulphuric acid solution was poured through the primary neck thus binding the water oxygen as zinc oxide, and … Continued

Chemistry: obtain hydrogen by dissociating water

A device to obtain hydrogen by dissociating water over glowing iron: the hot iron used the water oxygen to form an iron oxyde thus leaving the hydrogen free. An iron pipe filled with iron shavings was heated up in a … Continued
