Cho nước tác dụng với oxi trong điều kiện có ánh sáng và chất diệp lục thu được khí oxi thoát ra.
Sau đó dẫn khí oxi qua hidro thu được nước.
Cho nước tác dụng với canxi oxit thu được nước vôi trong.
Dẫn nước vôi trong qua axit axetic thu được muối canxi axetat và nước.
Cuối cùng điện phân nước ta thu được khí hidro.
