...well above what I was expecting, around 10.1 pH at 1+50 dilution.

Likely do well as a print developer. At high dilutions perhaps a good
compensating film developer. Possibly the pure ascorbate. Check
with the supplier. A. A. is decidedly Acid; around ph 3 IIRC. Dan

Usually the starch-iodine test is used in the "reverse direction" to test for oxidizing agents but this should work too. Be careful. Don't use containers you'll later want to use for food. If the blank and controls don't work as expected, I messed up Report back to us on how it works!

Thanks for the instructions. Hopefully, I'll get some time this week to test.

I've developed a roll of film with this and it appears to work well. Faster than standard PC-TEA.
