On electrolysis, water splits into
- A. positively charged hydrogen ions and negatively charged oxygen ions.
- B. negatively charged hydrogen ions and positively charged oxygen ions
- C. hydrogen and oxygen atoms having positive and negative charges respectively.
- D. hydrogen and oxygen atoms having negative and positive charges respectively.
Step-by-step solution
During the electrolysis of water, water molecules dissociate into H⁺ (positively charged hydrogen ions) and OH⁻ (hydroxide ions, which contain oxygen with a negative charge). At the cathode, H⁺ gains electrons to form H₂ gas; at the anode, OH⁻ loses electrons to form O₂ gas. Thus, the initial ionic species are positively charged hydrogen ions and negatively charged oxygen-containing ions.
