In 1874 Stas called attention to six modifications of silverbromide.
2
The molecules of silverbromide gradually aggregate together, forming larger and larger particles.
3
From aqueous alcoholic solutions blue sensitive silverbromide is precipitated.
4
A precipitate of silver chloride and silverbromide weighs 0.8132 gram.
5
Bromine gives one of silverbromide.
6
Their unequal reducibility; the blue sensitive silverbromide being reduced with much greater difficulty than the indigo sensitive variety.
7
The indigo sensitive silverbromide cannot be distributed through a gelatin solution, while the blue sensitive modification does so very readily.
8
The only necessary condition is that in precipitating indigo sensitive silverbromide the solutions must contain at least 96 per cent of alcohol.
9
By these silverbromide is obtained in a very fine state of division, ready to mix with gelatine and water in any proportion.
10
Two or three ounces of methylated spirit are now added to the vessel containing the silverbromide, and the latter well mixed with it.
11
The extraordinary sensitiveness of silverbromide in gelatin seemed the more remarkable since it was known that silverbromide in collodion is only moderately sensitive.
12
On heating in a current of chlorine, the silverbromide is converted to silver chloride, and the mixture loses 0.1450 gram in weight.
13
Silverbromide was prepared in many different ways.
14
Silverbromide is extensively used in photography, and the bromides of sodium and potassium are used as drugs.
