  Stop bath - Wikipedia, the free encyclopedia
Stop bath is the second of three chemical baths usually used in processing traditional fl-and-white photographic films, plates, and paper.
Stop bath accounts for the characteristic vinegar-like odor of the traditional darkroom, and in its concentrated form can cause chemical burns.
For indicator stop bath -- a stop bath that changes colours to indicate when the stop bath is exhausted and no longer effective -- the pH indicator bromothymol violet is used to determine when the solution has become too alkaline to use.

 ACID STOP BATH
Although a plain water rinse bath is commonly used between development and fixation, a better procedure is to use an acid stop bath.
The function of a stop bath is not only to remove the developer that is clinging to the surface of the material but to also neutralize the developer in the swollen emulsion to stop development completely.
Strong acid and the acid in the fixing bath have a tendency to form carbon dioxide gas bubbles in the emulsion.

Hot bath water is responsible for the highest number of fatal and severe scald injuries in the home.
Young children and older people are most at risk from bath water scalds because their skin is thinner and therefore less tolerant to higher water temperatures than that of other age groups.
Statistics are average yearly numbers of bath scalds by severity and age group in UK 1992-1996, Sambrook Research International 1999.

BLOCK may be converted into a hardening stop bath for sepia toning, or to replace hardening in the fixer if sulfur dioxide vapors must be minimized.

 Indicator stop bath failure
When the indicator stop bath loses it's vinegar smell, or starts turning dark, I splash some ordinary distilled vinegar into it until it turns lighter yellow and I can smell the vinegar again.
I suspect that your plain hypo bath is turning blue due to the carry- over of the indicator in your stop bath that turns blue in a more alkaline environment.
If your stop were the same pH as the plain hypo bath, it would also be blue and not function as intended.

 Peter Hogan - Specialist Black and White Products for fine photographers
Although it is more convenient to use an acid stop bath and fix, simply because they are more readily available, it is far better to keep the whole processing procedure at or near the ph of the developer, and developers are alkaline!
It is known that an acid environment inhibits the formation of the stain so desirable and effective in producing fine negatives, but keeping the ph within certain tolerances not only enhances the stain, but has other benefits too.
You do not need a hypo clearing bath for prints, and the toning qualities of prints will be enhanced too.

Already leading 22-9, Northampton absorbed wave after wave of Bath pressure before turning the ball over on their own line and mounting a counter-attack the length of the field.
All Bath could muster in the face of Northampton’s fast-moving pressure defence were three penalties from fly-half Chris Malone and a late consolation try for flanker Andy Beattie.
