a. In the first case?
b. In the second case​

Answer 1

Answer:

When an electric current is passed through water, “Electrolysis of water” occurs, which is the decomposition of water (H2O) into hydrogen gas (H2) and oxygen (O2). The reaction ideally requires a potential difference of 1.23 volts in order for the water molecules to split up
