Note 19 — Chapter II · THE COMPOSITION OF WATER, HYDROGEN
George Kamensky translation
The reaction expressed by the equation CNaHO2 + NaHO = CNa2O3 + H2 may be effected in a glass vessel, like the decomposition of copper carbonate or mercury oxide (see Introduction); it is non-reversible, and takes place without the presence of water, and therefore Pictet (see later) made use of it to obtain hydrogen under great pressure.
