Only about fifteen seconds. The purpose of the stop bath is to halt the development of the film, plate, or paper by either washing off the developing chemical or neutralizing it. A simple water rinse can be used between developer and fixer, but the development process continues (though possibly at a very low level) for an indefinite and uncontrolled period of time during the rinsing.
Stop bath will usually consist of some concentration of acetic acid, commonly around 1 to 2%. Since organic developers only work in alkaline solutions, stop bath halts the development process almost instantly and thus provides more precise control of the development time. It also cuts overall processing time, because the required immersion time in the stop bath is much shorter than the time required for an adequate plain-water rinse. As well, by neutralizing the alkalinity of basic developers, it can help to preserve the strength of the fixer, making it last longer.

What are the three basic chemicals needed to develop photographic paper?
For a properly exposed print, only two are absolutely required: The developer (alkaline) and the fixer (acidic). A stop bath (acidic) is used between the two by many who think it is necessary to arrest development. However, a properly exposed print differs from film in that once the exposed silver halide has been reduced to black metallic silver, more development time does not cause more reduction. The major benefit to the stop bath is that it neutralizes developer that would otherwise be carried over to the fixing bath, thus it prolongs the life of the reusable fixer. To be precise, this is the real reason for using the stop bath. Arresting development with a stop bath will often produce inconsistent results between prints of the same negative and exposure which are visible to the trained eye.
In photography are fixers stop bath and developer chemicals flammable?
The diluted solutions aren't flammable, but if you mix your stop bath and fixer using glacial acetic acid like I do, you should know glacial acetic acid is flammable.

What is the purpose of stop bath in film development?
It neutralizes the developer, and stops it from working any more than it already has. It also lengthens the useful life of fixer (the next step in B&W developing) by preventing the alkaline developer from contaminating the acid fixer. In B&W print development, it serves that purpose more so as a properly, exactly exposed print does not need a stop bath to arrest development. If you're running Process E-6, it has another function. (Note: the official Kodak E-6 process doesn't contain a stop bath after either developer, but I use one after the first developer.) The second step in six-step E-6 is reversal bath. Kodak's reversal bath liberates a LOT of gas if you use it with no stop bath beforehand, and it will blow the cover off your tank.

What is acetic acid used for in a darkroom?
Acetic acid, also known as vinegar, is used in a darkroom as a stop bath solution to halt the development process of photographic prints. It helps neutralize the alkaline developer solution, preventing further development of the image on the print.
