# When electric current is passed through acidulated water, the hydrogen and oxygen gases separate. Which electrode do the hydrogen ions move to and why

1. As we know,the hydrogen ions H+ are positive in nature.
2. Thus they are attracted by the negative end of the electrode i.,e anode as it is negatively charges and undergoes the following reaction :

2 H+ + 2e- $\to$ H2

Electrolysis of water is the decomposition of water (H2O) into oxygen (O2) and hydrogen gas (H2) due to an electric current being passed through the water.

This technique can be used to make hydrogen fuel (hydrogen gas) and breathable oxygen; though currently most industrial methods make hydrogen fuel from natural gas instead.

hydrogen moves to anode and oxygen remains in water
