If current is passed in an electrolytic cell containing sodi

If current is passed in an electrolytic cell containing sodium nitrate, NaNO3, dissolved in water, what are the products at the anode and cathode? Explain I believe the products are O2 gas at anode and H2 gas at cathode but not sure how to explain it.

H2O is easier to electrolyze than Na and NO3^-. The NaNO3 serves as an electrolyte to conduct electrons from electrode to electrode but the NaNO3 stays intact as the ions.
