The subsequent procedure is the same as when aqueous ammonia is used.
2
Wash the filter five times with water, and finally pour through it aqueous ammonia.
3
When the acid is dissolved, add gradually concentrated aqueous ammonia, just enough to neutralize the solution-170volumes, about.
4
It is least soluble in a liquid containing one fourth of its volume of concentrated aqueous ammonia (sp.

If they were developed with silver, they must be immersed in diluted aqueous ammonia, which will perfectly clear the whites.
6
Add aqueous ammonia (sp.

To remove the chromium compound the picture is immersed in a solution of aqueous ammonia, 1:6, then washed and dried.
