I'm not GREAT at chemistry, but it occurred to me that within... for example the 3 bath kits, there's multiple chemicals. In each bath.

Not ALL the chemicals within each bath may go bad right? Only some?

So is it possible, say I own a 1 L kit, my first developer goes bad after... 12 rolls but it goes bad from TIME ... I did 12 rolls, now it sat in my basement for 3 months, the color developer and bleach are probably good right but the first developer is bad? (Correct me on which goes bad first if I'm wrong, I tend to forget these things or mix them up).

So if I own certain powder chemicals, could I pour in some of those to reactivate the first developer? Since some of the stuff in there is good it's just certain parts of the mix that go bad?
