Iodine screw up

(1/4) > >>

tina_craig:
Is there anything one can do if too much acid was added to 9.4% tincture 1 pint, added 200mL instead of 2 oz.

jboogie:
i never really measure that precicely when crashing iodine. i just add equal parts of hcl and peroixde. adding more of either never increased or decreased yeilds for me. but im not a chemist, i just follow directions well.

geezmeister:
Dilute with more water; you will already have crystals by the time I post this reply.... just remember to rinse that I2 very very well to remove all the traces of HCl from it. Otherwise the I2 will degrade rapidly, likely as you try to dry it in a coffee filter... and a large portion of it will remain in the coffee filter as black sludge.

wareami:
Ibee made that mistake of adding too much HCL once to 2% tinc and it turned the solution clear...never to be seen again.
Did the same thing with too much h2o2 once...same thing! Turned clear....never to be seen again.

Adding h2o didn't help in Ibee's case.

Geez if the excess h2o fails to produce I2 xtals could T_C try this?

My idea in hindsight, since Ibee trashed that botched excess acid tinker, he didn't try this but might now if faced with the same invisible crstals:
If the xtals won't precipitate in solution, couldn't one try to nueutralize the excess acid with NAOH to account for the excess 141ml hcl

2oz=59ml
6.7oz=200ml

geezmeister:
Past experience suggests that for 9.7% tincture the amount of HCl is too much, but not so much that you can't get crystals.  I know folks who use that much acid on a pint of  7?% tinc. Two percent? That would be WAY too much HCl... and you would have sludge when you were done, if anything.

You can bring the pH up and neutralize the acid with NaOH... but if you use crystals after doing this, be sure to resublime them before use. The crystals always seem to have some base in them if you don't resublime them... even with repeated washings with dH2O... and that will impact the reaction in a negative way.
