On electrolysis, water splits into

1. positively charged hydrogen ions and negatively charged oxygen ions.
2. negatively charged hydrogen ions and positively charged oxygen ions
3. hydrogen and oxygen atoms having positive and negative charges respectively.
4. hydrogen and oxygen atoms having negative and positive charges respectively.

Correct answer: positively charged hydrogen ions and negatively charged oxygen ions.

Solution

During electrolysis, water is split into ions rather than neutral atoms. The hydrogen part becomes positively charged, while the oxygen-containing part becomes negatively charged, matching the ionic nature of the process.
