Yes, H2 and O2 can be separated from H2O through electrolysis. This process involves passing an electric current through water, causing it to decompose into hydrogen and oxygen gas. To do this, set up an electrolytic cell with water and a suitable electrolyte, such as salt, then apply a direct current. Hydrogen gas will collect at the cathode (negative electrode), and oxygen gas will collect at the anode (positive electrode). Handle the gases with care, as they are highly flammable.
FAQs & Answers
- What is electrolysis? Electrolysis is a chemical process that uses an electric current to drive a non-spontaneous reaction, such as splitting water into hydrogen and oxygen.
- Is it safe to handle hydrogen and oxygen gases? Yes, but you must handle them with care, as both gases are flammable; proper safety precautions should always be taken.
- What equipment do I need for electrolysis? You will need an electrolytic cell, water, a suitable electrolyte (like salt), and a direct current power source.
- What happens at the electrodes during electrolysis? Hydrogen gas collects at the cathode (negative electrode) and oxygen gas collects at the anode (positive electrode).
