The main purpose of having two parts for ID-11 is for ease of mixing, so if you got it to dissolve, then you should have proper working developer.(posted 8434 days ago)There is one minor issue, though. Some of the preservatives are in the Part A, so the Part B might have started to oxidize a little faster than normal before the Part A was added. So while the developer should work fine, you may have a shortened shelf life of the solution.
