These are my thoughts, but I haven't studied chemistry for over 40 years :-D
NaCl is an electrolyte when molten and also when placed in a solvent (water) to form an ionic solution.
Distilled water is not an electrolyte as it doesn't contain free ions.
I don't think hydrogen peroxide is an electrolyte. It spontaneously decomposes into water and oxygen gas. Traces of metal ions in peroxide leads to catalytic decomposition or explosion.
CO2 when dissolved in water produces hydrogen carbonate ions, so I guess would then be classed as an ionic solution.
Oxidized copper when placed in an acid (like vinegar when you try to clean coins) which dissolves the oxide, I guess, would produce a solution that could be electrolytic.
Hope this helps.
