Hydrogen fuel is a combination of air, water, and natural gas and is commonly used to create electricity. Electricity is generated when the gas is mixed with oxygen to create water. Moreover, it is also possible to divide water into oxygen and hydrogen by passing an electric current through it. In other words, it is the decomposition of H2O into O2 and H2. To make hydrogen fuel at home, follow the steps below. Remember, however, electrolysis or application of electric current is not a commercially viable method to produce hydrogen.
Step 1: Hoffman Volta-Meter
The Hoffman Volta-meter device is a "U" shaped glass tubing that includes an added fragment in the center and two on the sides of the center piping. The tube is open in the middle and the top. It has electrodes underneath, that find a way out through the waterproof holes. The device is often used as a small-scale electrolytic cell. When a current is passed through the device, an oxygen gas is formed at the anode and a hydrogen gas is formed at the cathode. The gases move water and are collected at the top of the tubes on the side. This device can be purchased from most hardware, DIY, and home improvement stores.
Step 2: Electrolytic Solution
The electrolytic solution would help generate electricity. This can be made by combining 4 parts water and 1 part sodium hydroxide in a large beater. The measurement must be done by weight. Stir thoroughly until the particles have been dissolved completely. The solution needs to be poured in the center pipe of the Hoffman Volta-metre.
Step 3: Submerging the Test Tube in Water
Pack another beaker with water and fill the test tube by sinking it in the water. Make sure no air bubbles are formed. Turn the test tube upside down. Hang the test tube in the water beaker with the assistance of a test tube holder. The procedure must be repeated for the other test tube as well.
Step 4: Filling Water in the Rubber Hose
Fill the rubber hosepipe with water. Place one end of the hosepipe in the beaker solution in the side tube of the volta-metre. Position the other end of the rubber hose in an overturned test tube just as you did in step 3. Repeat the process with the other side of the volta-metre tube.
Step 5: Connecting the Electrodes
Join the electrodes of the volta-metre with a battery. Monitor the bubbles that are composed in the electrode. The bubbles on the positive side of the electrode are hydrogen and the negative side of the electrode is oxygen. The gas bubbles would rise up and run through the hosepipe. As they shift into the test tube, they would shift the water in the test tube. Once the test tube is filled with gas, they can be conserved with a stopper for using later.
