%X When molten NaNO2 is electrolysed between copper electrodes, a yellow precipitate which contains copper(1) forms at the cathode.It seems probable that a cuprite with the empirical formula Na2O,Cu2O,H2O is initially formed and is then slowly oxidized either by species present in the melt or by air. If sufficient Na2O2 is added to saturate the melt (i.e., solid Na2O2 is present),the precipitate partly dissolves to form an orange-red solution which forms a green solid on freezing. This may contain a copper(11) or copper(111) cuprate.
