Davy decomposed water which had been purified by distillation , in glass vessels
, by passing an electric current through it ; in every case a little acid was
produced at the positive electrode , and a little alkali at the negative electrode .

But the result was as before ; traces of acid and alkali were produced . He used
electrodes made of different materials ; the results were the same . He distilled
the water again ; there was rather less alkali , but as much acid as before .
