What does activators do for the penetration of reducing agents?
A. Breaks a "door" in order to make it easier to penetrate.
B. Swells gelatin making it easier to penetrate
C. Blocks reducing agents in order for them to not release free electrons to silver ions.

A. Typically potassium brommide to provide distraction for overactive reducers.
B. Typically potassium sulfate which provides a distraction to activators
C. Typically sodium bicarbonate which provides a distraction to slow reducers.
D. Prevents developer from acting on unexposed silver halide crystals

True or false: Preservatives are typically sodium sulfite and decreases oxidation made by air.

What is the hardener responsible for?
A. For controlling swelling of gelatin
B. For preventing abrasions during processing
C. Maintaning uniform film thickness.

What does the "fixing" stage have differently than the "developing" stage?
A. Fixing stage has activators and developing doesnt.
B. Fixing has clearing agents while developing has reducing agents.
C. Developing has a solvent and fixing doesnt.

What does the clearing agent in the "fixing" stage do?
A. Bonds with developed silver halides.
B. Melts the chemistry away from the film.
C. Bonds wit unexposed silver halides becoming thiosilversulfate

What does activator in the "fixing" stage do?
A. enhances the action of reducers.
B. stops developing process
C. Stops action of reducers
D. None of the above

In the "fixing stage" what does preservatives do?
A. Removes silver from ammonium thiosilversulfate to allow ammonium thiosulfate to continue to remove silver halides.
B. Remove ammonium from thiosilversulfate to further increase quality of removement of silver halides.
C. It stops it from oxidizing.
D. None of the above.

True or False: The hardener for the "fixing" stage does something completely different than the "developers" stage.
True False
