The picture shows stepwise process how equipment are used to make hydrogen.
Overall, this is a basic laboratory experiment to get hydrogen gas. All the components are added in glass cylinder and then connects pipe to procced next phase to produce pure hydrogen gas.
The process starts by pouring hydrochloric acid of 5ml through thistle funnel that end must be below the tap water, in 50ml graduated glass cylinder filled with water(5ml) plus zinc of one gram. Further, through cork’s gap to insert water through glass pipe from dish. Furthermore, the cylinder mixing acid and water with zinc and water is passed through pipe.
Here, after first phase, the pipe is connected to a test tube which filled by water and dish that include sufficient water. Further, tube produce hydrogen gas after mixed water through acid comes . In order to completing whole process gives a hydrogen gas through laboratory equipment by using different vessel, acid and water.
