View Full Version : What happened when I mixed ID-11 (calling on ID-11 users)

I mixed up a 5-L volume of ID-11 a few days ago. This was the first time with ID-11. Mixed at 40 C (104 F). When fully mixed per instructions for Parts A and B, I noticed that the solution had a very slight brown tint. Very slight, but the kind of brown color that I associate with developer oxidation, as with D-76. Does this happen to you?

(We recently had an arsenic removal system installed to treat the water to the whole house. This system uses entrained air in one of the processes. If no one else reading this finds their freshly mixed ID-11 ever-so-slightly brown, I probably should conclude that I didn't let the water de-gas sufficiently.)

Thank you for the help! This is a great site!

You can actively de-gas the water by heating it to ~80C. Whatever that is in your local units.

Yes, when i mix ID-11 in 5l quantities, it does have a slight brown colour, so I'd say this was quite normal.

Honestly I cannot say but one test will tell you by putting a roll through the process.
I used d76 for 35 years and switched to ID 11 and I found them identical.. I do know the Developer Container 20 litre is stained brown over years of use.

I think you will be ok. I think its a great all round developer.

Sounds completely normal. I've processed hundreds of rolls with ID-11 and mixed up many batches. It's not crystal clear like water when mixed. There's a very slight pale yellow or yellow/brown tint to it. Keep it in air free containers in a dark place, and it will be fine to use for six months or more.

I've rarely used D76, but when I did it had a brown tinge to it when freshly mixed--I'd say this is normal. If I recall, Dektol does, too. Maybe it's typical of MQ developers? I've tended more to use liquid concentrates in the past, and now, mixed from raw chemicals. I always use distilled water for developers, now.

Its not D-76 or ID-11, but I just mixed up a batch of Divided D-23. When I dropped the Metol (which is also in D-76 and ID-11) into the water, it turned brown and slowly faded to a sort of light yellow/amber color.

I've been mixing ID11 for over 30 years and the colour of fresh ID11 seems to change slightly with every batch.

A pale tan colour is nothing to be concerned about.
