Bromide Printing and Enlarging A Practical Guide to the Making of Bromide Prints by Contact and Bromide Enlarging by Daylight and Artificial Light, With the Toning of Bromide Prints and Enlargements If a silver bromide paper is used in making the print, a latent image is produced which must be developed as in the case of the negative itself. An Elementary Study of Chemistry The majority are soluble in water, the chief exceptions being silver bromide, mercurous bromide, palladious bromide and lead bromide; the last is, however, soluble in hot water. Encyclopaedia Britannica, 11th Edition, Volume 4, Part 3 "Brescia" to "Bulgaria" In the case of the silver bromide a distinct photo-electric effect is still observed. The Birth-Time of the World and Other Scientific Essays Calculate the minimum concentration of ammonia needed in 1.0 L of solution to dissolve 3.0 10–3 mol of silver bromide. Chemistry 2019-02-14T00:00:00Z One gram of a mixture of silver chloride and silver bromide is found to contain 0.6635 gram of silver. An Introductory Course of Quantitative Chemical Analysis With Explanatory Notes The silver bromide is much more sensitive than the chloride, so that the printing can be done in artificial light. An Elementary Study of Chemistry Silver nitrate in the presence of nitric acid gives with bromides a pale yellow precipitate of silver bromide, AgBr, which is sparingly soluble in ammonia. Encyclopaedia Britannica, 11th Edition, Volume 4, Part 3 "Brescia" to "Bulgaria" The molecules of silver bromide gradually aggregate together, forming larger and larger particles. Scientific American Supplement, No. 384, May 12, 1883 Normally the solubility increases and some of the solid silver bromide will dissolve. Chemistry 2019-02-14T00:00:00Z A precipitate of silver chloride and silver bromide weighs 0.8132 gram. An Introductory Course of Quantitative Chemical Analysis With Explanatory Notes The extraordinary sensitiveness of silver bromide in gelatin seemed the more remarkable since it was known that silver bromide in collodion is only moderately sensitive. Scientific American Supplement, No. 401, September 8, 1883 For their quantitative determination they are precipitated in nitric acid solution by means of silver nitrate, and the silver bromide well washed, dried and weighed. Encyclopaedia Britannica, 11th Edition, Volume 4, Part 3 "Brescia" to "Bulgaria" If such an emulsion be boiled, we shall find the remarkable fact that, however long it be boiled, the silver bromide undergoes no change, neither does the emulsion become any more sensitive. Scientific American Supplement, No. 384, May 12, 1883 Note the chloride ion concentration of the initial mixture was significantly greater than the bromide ion concentration, and so silver chloride precipitated first despite having a Ksp greater than that of silver bromide. Chemistry 2019-02-14T00:00:00Z On heating in a current of chlorine, the silver bromide is converted to silver chloride, and the mixture loses 0.1450 gram in weight. An Introductory Course of Quantitative Chemical Analysis With Explanatory Notes The explanation was sought for in various directions, but as the result of numerous investigations it appears that the chief cause of the difference is the presence of different modifications of silver bromide. Scientific American Supplement, No. 401, September 8, 1883 Thus the positive process of carbon printing would be modified in such a manner that the mixtures containing the permanent pigment should be sensitized with silver bromide in place of potassium bichromate. Scientific American Supplement, No. 286, June 25, 1881 Another action of chromic acid is, that it destroys the action of light on silver bromide, so that up to this point operations can be carried on in broad daylight. Scientific American Supplement, No. 384, May 12, 1883 At one time, light-sensitive silver bromide was a component of photographic film. Chemistry 2019-02-14T00:00:00Z The silver bromide obtained by his process is not highly sensitive, and requires boiling with gelatine before it is in a fit state to make a rapid plate. Scientific American Supplement, No. 303, October 22, 1881 The result of all these experiments is that there are essentially two modifications of silver bromide, the one being obtained by precipitation in aqueous, the other in alcoholic solutions. Scientific American Supplement, No. 401, September 8, 1883 From aqueous alcoholic solutions blue sensitive silver bromide is precipitated. Scientific American Supplement, No. 401, September 8, 1883 The indigo sensitive silver bromide cannot be distributed through a gelatin solution, while the blue sensitive modification does so very readily. 2d. Scientific American Supplement, No. 401, September 8, 1883 Their unequal reducibility; the blue sensitive silver bromide being reduced with much greater difficulty than the indigo sensitive variety. 3d. Scientific American Supplement, No. 401, September 8, 1883 The amount of alcohol used is comparatively small; in fact, to prepare silver bromide for a pint of emulsion very little more than a pint of methylated spirit is required. Scientific American Supplement, No. 303, October 22, 1881 It makes no difference whether the solution is hot or cold, or whether the silver bromide is treated with ammonia or whether it is boiled or not. Scientific American Supplement, No. 401, September 8, 1883 Now the blue sensitive silver bromide has a greater absorption power than the indigo sensitive variety, and hence its greater sensitiveness. Scientific American Supplement, No. 401, September 8, 1883 By these silver bromide is obtained in a very fine state of division, ready to mix with gelatine and water in any proportion. Scientific American Supplement, No. 303, October 22, 1881 Two or three ounces of methylated spirit are now added to the vessel containing the silver bromide, and the latter well mixed with it. Scientific American Supplement, No. 303, October 22, 1881 With a view of doing away with the washing altogether, or, rather, of washing of the silver bromide when not incorporated with the gelatine, several processes have been invented. Scientific American Supplement, No. 303, October 22, 1881 The only necessary condition is that in precipitating indigo sensitive silver bromide the solutions must contain at least 96 per cent of alcohol.
