• But fabrics immersed in a bleaching powder solution do not lose their color as would naturally be expected. Bertha M. Clark. General Science.
• 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. Bertha M. Clark. General Science.
• 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. Bertha M. Clark. General Science.
• An enormous quantity of sodium carbonate, or soda, as it is usually called, is needed in the manufacture of glass, soap, bleaching powders, and other commercial products. Bertha M. Clark. General Science.
• The harmless nature of sulphurous acid makes it very desirable as a bleaching agent, especially in the home. Bertha M. Clark. General Science.
• As the moist material is drawn through the bleaching solution, the acid on the fabric acts upon the solution and releases chlorine. Bertha M. Clark. General Science.
• That this solution has bleaching properties is shown by the fact that a colored cloth dipped into it loses its color, and unbleached fabrics immersed in it are whitened. Bertha M. Clark. General Science.
• In like ways, chemistry grew out of processes of dying, bleaching, metal working, etc. John Dewey. Democracy and Education.
• The art of bleaching coloured stock was unknown, and white paper was made alone from stock that came white into the mill. William Henry Doolittle. Inventions in the Century.
• 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. Bertha M. Clark. General Science.
• Some of the compounds formed by the sulphurous acid bleaching process are gradually decomposed by sunlight, and in consequence the original color is in time partially restored. Bertha M. Clark. General Science.
• The material to be bleached is drawn through an acid _a_, then through a bleaching solution _b_, and finally through a neutralizing solution _c_. Bertha M. Clark. General Science.
• The substance almost universally used as a rapid artificial bleaching agent is chlorine, best known to us as a constituent of common salt. Bertha M. Clark. General Science.
• About this time, both in England and America, machines had been devised for sewing lengths of calico and other cloths together, previous to bleaching, dyeing or printing. William Henry Doolittle. Inventions in the Century.
• This tendency of chlorine to combine with hydrogen makes it valuable as a bleaching agent. Bertha M. Clark. General Science.
• This mild form of a bleaching substance has been put to uses which are now prohibited by the pure food laws. Bertha M. Clark. General Science.
• The manufacture of soap, glass, bleaching powders, baking powders, washing soda, and other chemicals depends on salt, and it is for these that the salt beds are mined. Bertha M. Clark. General Science.
• Bleaching powder is very useful in the removal of stains from white fabrics. Bertha M. Clark. General Science.
