SOLVENT
MEDIUM IN WHICH OTHER CHEMICALS ARE DISSOLVED OR SUSPENDED.

8. WETTING AGENT
AGENT CAUSING THE GELATIN OF THE FILM EMULSION TO SWELL AND ALLOWS REACTION OF THE DEVELOPER CHEMICALS WITH THE FILM EMULSION COMPONENTS.

9. FUNCTION OF DEVELOPER
CONVERSION OF THE IONIC CHAINS OF SILVER INTO BLACK METALLIC SILVER
Ag+1+ -e Ag0

13. REDUCING AGENTS
SUPPLY ELECTRONS FOR REDUCTION OF IONIC SILVER INTO METALLIC FORM.
PHENIDONE –ACTS QUICKLY, PRODUCES GRAY TONES IN THE IMAGE.
HYDROQUINONE– ACTS SLOWLY, PRODUCES BLACK TONES IN THE IMAGE

14. HYDROQUINONE + PHENIDONE SYNERGISTIC REACTION ( WORK TOGETHER TO PRODUCE THE MANIFEST IMAGE.

26. FIXING AGENT ( CLEARING)
REMOVES UNDEVELOPED AgBr
FROM EMULSION.

27. HYPORETENTION
RETENTION OF THE FIXING AGENT IN THE EMULSION. IT PRODUCES BROWN DISCOLORATION ON THE FILM. IT CAUSES POOR ARCHIVAL QUALITY OF THE FILM.

28. HYPORETENTION

29. ACTIVATOR
STOPS THE DEVELOPMENT PROCESS BY PRODUCING ACIDIC Ph. IT NEUTRALIZES RESIDUAL DEVELOPER.
