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 are the essential chemicals needed by a film developer to process film, including stop bath and fixer?
The essential chemicals needed by a film developer to process film include developer solution, stop bath, and fixer. The developer solution develops the latent image on the film, the stop bath halts the development process, and the fixer stabilizes the image and makes it permanent.
How can I develop film negatives at home?
To develop film negatives at home, you will need a darkroom or a light-tight space, developer chemicals, stop bath, fixer, and a film developing tank. First, load the film into the tank in complete darkness. Then, follow the instructions on the developer chemicals to develop the film. After developing, rinse the film with stop bath and fixer to stop the development process and make the image permanent. Finally, wash the film thoroughly with water and hang it to dry.

How to process 35mm film at home?
To process 35mm film at home, you will need a developing tank, chemicals (developer, stop bath, fixer), a thermometer, and a darkroom or changing bag. First, load the film into the developing tank in complete darkness. Mix the chemicals according to the instructions and maintain the correct temperature. Develop the film by agitating it in the developer for the specified time. Stop the development process with the stop bath, then fix the image with the fixer. Rinse the film thoroughly and hang it to dry.
How long does a print need to be in a stop bath?
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.
What is meant by ice bath after blanching?
An ice bath is where you take whatever you just blanched and put it in ice water. The purpose is to stop the blanched item from cooking/softening.
How can I develop a film roll using traditional methods?
To develop a film roll using traditional methods, you will need a darkroom, developer chemicals, stop bath, fixer, and water. Start by loading the film onto a reel in complete darkness, then immerse it in developer for the specified time. Next, rinse in stop bath, fix the image in fixer, and wash in water. Finally, hang the film to dry.
What equipment do you need to develop film?
To develop film, you will need a darkroom or a light-tight changing bag, film developing tanks, film developing chemicals (developer, stop bath, fixer), a thermometer, a timer, and a film squeegee or clips for hanging the film to dry.
How can you stop a bath leak?
with A bath Will stop leaking. If you would simpoly place the plug in the plughole.
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.
What are the steps to properly develop an exposed film roll?
To properly develop an exposed film roll, follow these steps: Prepare the necessary chemicals and equipment in a darkroom or light-tight changing bag. Remove the film from the camera and transfer it to a developing tank. Mix the developer solution according to the instructions and pour it into the tank. Agitate the tank at regular intervals to ensure even development. Rinse the film with stop bath to halt the development process. Fix the film with a fixing solution to make the image permanent. Rinse the film thoroughly with water and hang it to dry in a dust-free environment.
