does water electrolysis works in tap water or distilled water better?
tell me the answer and i would like to know if this is good enough for a 9th grade science project If it is not then tell me a 9th-10th grade project on water elctrolysis.

if u can capture all the gas then turn it upside down it will force the oxygen out but keep hydrogen in and then u can test the bowl for hydrogen

Electrolysis is a Chemical change, especially decomposition, produced in an electrolyte by an electric current. The word electrolysis means the process of breaking molecules to smaller components by using an electric current. Positive and negative poles of a DC electric source such as a battery can absorb opposite ions of an electrolyte causing separation of ions and creation of a new substance.
Electrolytes dissolve by dissociation. That is when the molecules of a substance break down into charged particles called ions. An ion with a negative charge is called an anion because it is drawn through the solution to the positive charge on the anode. A particle with a positive charge is called a cation. It moves through the solution to the cathode. Water has its solvent properties because it is polar. The molecule has charged ends (+ and -). These charged ends react with charges on other polar substances to dissolve them. They do so by taking hydrogen atoms from the substance to form hydrogen ions. The word electrolysis means the process of breaking molecules to smaller components by using an electric current. Positive and negative poles of a DC electric source such as a battery can absorb opposite ions of an electrolyte causing separation of ions and creation of a new substance.
