“If the two wires from a battery be placed in pure water, it will be foud tat practically no current passes...If a small quantity of sulphuric acid is added to the water, the solution is a good conductor. During the passage of current, bubbles form at the ends of the wires: at the positive electrode (anode)...oxygen appear[s]; at the negative electrode (cathode) there is a rapid evolution of hydrogen.” -Brownlee 1907
