whats the breakdown of water to form two gases is the result of this process?
electrolysis
The breakdown of water to form two gases is known as water electrolysis, and the result of this process is the production of hydrogen gas (H2) and oxygen gas (O2).
Now, I'll explain how the breakdown of water to form these two gases can be achieved through water electrolysis:
1. Setting up the electrolysis apparatus: In order to perform water electrolysis, you would need an electrolysis apparatus consisting of two electrodes: a positive electrode (anode) and a negative electrode (cathode). These electrodes are usually made of inert materials like platinum or graphite. The two electrodes are placed in a container filled with water, which acts as an electrolyte.
2. Applying an electric current: Next, a direct current (DC) power source, such as a battery or a power supply, is connected to the two electrodes. The positive electrode (anode) is connected to the positive terminal of the power source, while the negative electrode (cathode) is connected to the negative terminal. This creates a closed circuit for the electric current to flow.
3. Electrolysis process: When the electric current is applied, the water molecules (H2O) start to undergo a redox reaction at the electrodes. At the anode, the water molecules lose electrons and release oxygen gas (O2). The reaction at the anode can be represented as: 2H2O(l) -> O2(g) + 4H+(aq) + 4e-
4. At the cathode, the water molecules gain electrons and produce hydrogen gas (H2). The reaction at the cathode can be represented as: 4H2O(l) + 4e- -> 2H2(g) + 4OH-(aq)
5. Collecting the gases: As the electrolysis continues, the hydrogen gas will collect at the cathode, while the oxygen gas will collect at the anode. These gases can be collected separately using appropriate gas collection methods.
6. Safety precautions: It's important to note that water electrolysis involves the use of electricity and can be potentially dangerous. Safety precautions must be followed, such as using low voltage power sources, ensuring proper ventilation, and using appropriate materials for electrodes and containers.
So, in summary, the breakdown of water to form two gases (hydrogen and oxygen) can be achieved by setting up an electrolysis apparatus, applying an electric current, and collecting the resulting gases at the respective electrodes.
