• For example, if the sun's rays fall upon silver chloride, a chemical action immediately begins, and as a result we have two separate substances, chlorine and silver. 伯莎M.克拉克. 科学通论.
• Free chlorine is heavier than air, and hence when it leaves the exit tube it settles at the bottom of the jar, displacing the air, and finally filling the bottle. 伯莎M.克拉克. 科学通论.
• The acid used to liberate the chlorine from the bleaching powder, and the chlorine also, rot materials with which they remain in contact for any length of time. 伯莎M.克拉克. 科学通论.
• By experiment it has been found that the addition to the bleaching solution of an acid, such as vinegar or lemon juice or sulphuric acid, causes the liberation of the chlorine. 伯莎M.克拉克. 科学通论.
• Silk, lace, and wool when bleached with chlorine become hard and brittle, but when whitened with sulphurous acid, they retain their natural characteristics. 伯莎M.克拉克. 科学通论.
• Chloride of lime when exposed to the air and moisture slowly gives off chlorine, and can be used as a disinfectant because the gas thus set free attacks germs and destroys them. 伯莎M.克拉克. 科学通论.
• It is soluble in nitromuriatic acid and in a solution of chlorine. 佚名. 神奇的知识之书.
• The production of caustic soda, sodium carbonate, and chlorine by the electrolysis of brine, is carried on upon a large scale, and will probably supersede all other methods. Edward W. Byrn. 十九世纪发明进展.
• As the moist material is drawn through the bleaching solution, the acid on the fabric acts upon the solution and releases chlorine. 伯莎M.克拉克. 科学通论.
• The manganese itself combines with part of the chlorine originally in the acid, but not with all. 伯莎M.克拉克. 科学通论.
• The presence of these nitrogen compounds influences the action of the chlorine and produces unsatisfactory results. 伯莎M.克拉克. 科学通论.
• For animal fibers it is therefore necessary to discard chlorine as a bleaching agent, and to substitute a substance which will have a less disastrous action upon the fibers. 伯莎M.克拉克. 科学通论.
• Of all the vast group of salts, the most abundant as well as the most important is common salt, known technically as sodium chloride because of its two constituents, sodium and chlorine. 伯莎M.克拉克. 科学通论.
• The chlorine liberates oxygen from the water. 伯莎M.克拉克. 科学通论.
• In the dark, chlorine and hydrogen are simply chlorine and hydrogen; in the sunlight they combine as if by magic into a totally different substance. 伯莎M.克拉克. 科学通论.
