Hi I prepared an ammonium acetate solution by adding some phenolphthalein solution to the ammonia, Then adding vinegar till the pink went away. I then
boiled it down and now the solution is a dark red solution. Do you know why this may be?
Thanks.
It was household vinegar and ammonia.

You ended up with an excess of ammonia, which is very common. It probably shouldn't be an issue. smaerd - 18-4-2014 at 11:07
Try adding some cold anhydrous alcohol (ethanol, methanol, isopropanol/whatever) to your 'ammonium acetate'. See if it's the phenolphthalein.
I didn't do anything to it. That makes me think that some carbon monoxide might've came off from the decomposition of the phenolphthalein.smaerd - 18-4-2014 at 11:51
Looks like some very charred organic material (phenolphthalein).
It was ammonium acetate.copperastic - 18-4-2014 at 13:22
Also i added 2 drops of 1 percent solution of phenolphaethlien in isopropanol.
I think I spelled those 2 chemicals wrong...thesmug - 18-4-2014 at 13:46
Isopropanol is right, phenolphthalien, you replaced the th with aethcopperastic - 18-4-2014 at 13:48
That's weird it said isopropanol was spelled wrong.vmelkon - 21-4-2014 at 06:10
So why don't you do the experiment again with the amounts that you know for ammonia and vinegar and this time, don't add the phenolphthalien.
