Preparation.--This is easily accomplished by putting about two parts of hydrochloric (muriatic) acid on one of powdered black oxide of manganese, and heating it gradually in a flask or retort, to which may be adapted a bent glass tube. A yellowish-green gas is disengaged, which being conducted through the glass tube to the bottom of a bottle, can readily be collected, being much heavier than the air, displaces it completely and the bottle is filled (which can be seen by the green color); a greased stopper is tightly fitted to it, and another bottle may be substituted.英文原著 · 《American Hand Book of the Daguerreotype》
"They may be made directly from either metal by dissolving it in hydrochloric acid; but they may be formed by a cheaper method, and by which also the acid fumes are avoided.英文原著 · 《American Hand Book of the Daguerreotype》
The action of light both combines and decomposes bodies. For instance, chlorine and hydrogen will remain in a glass vessel without alteration if kept in the dark; but if exposed to the rays of the sun, they immediately enter into combination, and produce hydrochloric acid. On the other hand, if colorless nitric acid be exposed to the sun, it becomes yellow, then changes to red, and oxygen is liberated by the partial decomposition effected by the solar rays.英文原著 · 《The History and Practice of the Art of Photography》
The vial fell and cracked on the table. The hydrochloric acid spread out over Marshall's will. And under the chemical reagent the figure in the bequest of fifty thousand dollars changed beautifully; the bar of the 5 turned blue, and the remainder of it a deep purple-red like the body of the will. "Gaeki," cried my father, "you have trapped a rogue!" "And I have lost a measure of good acid," replied the old man. And he began to gather up the bits of his broken bottle from the table.英文原著 · 《The Sleuth of St. James Street》
