question about methyl orange | Bookmark | ||||||
I have this nice liter of methyl orange, and wanted to know if I use it as a titration indicator for creating the hydrochloride, will it leave a residue that will screw up the final product... or do I need to remove it somehow... I saw that sunlight used it in one synth, and was curious about the correct procedure (not the titration but the processing)... tfse did not indicate anything Me-Orange..

Yeah works great! | Bookmark | ||||||
Yeah, I've written about methyl orange in a few posts. It's a great titration end-point indicator. What I do is put a couple drops onto paper towel, then take a sample of the aqueous layer I'm examining (after it settles from mag stirring), and drop a bit of the aqueous onto the spot on the paper towel. If it goes red, then I've added enough acid to extract all of the amine from the non-polar... This idea works well with other indicators too. (inc the ones made from red cabbage, etc) |

Thanks! | Bookmark | ||||||
Ah, an excellent method... I did read all your posts on cabbage and paper towels... very good btw... I didn't think to extrapolate it to sample spotting, but of course... Infinite Radiant Light - THKRA |
