defining acid name ?
« on: August 10, 2010, 11:30:57 AM »
so i have a solution that contain :
-acid (acetic acid / ascorbic acid /not acetic acid and ascorbic acid )

so how can i define what acid is that ?

my first thought is to add some baking soda :D and it will make CO2 gasses which make sizzling sound :D but both acetic and ascorbic acid can do that :( so i can't know is it acetic or ascorbic acid :(

how can i test for acetic acid ?
how can i test for ascorbic acid ?

Are these acids involved in redox reactions?

Edit to clarify: do you know IF these acids CAN undergo redox reactions?

I think it's obvious but I'm a bit confused, are you saying there is ascorbic acid OR acetic acid and you don't know which?

If so, could you just try a titration?

yes it can do redox reaction :D
cause i also use it to make volta element

doing a titration ? i don't know how to do it :(
the first i think is to make sodium acetate and make it into "hot ice"
but when i try to make hot ice using vinegar and baking soda
i can't :( so i guess that i can't make hot ice :(
now i get really confuse

the second idea come to my mind is using soda water and phospate
i mix soda water and phospate and heat it :D it makes cloudy solution :D
and when you gives asetic acid it make that solution cloudiness
so how you think ?

 can i test asectic acid using phospate and soda water ?

it is the same theory that used in asetic acid heat test
"The sample (10 cc urine)is boiled and if these are present the urine turns cloudy. Acetic acid is introduced, a drop or two of 5-10% acetic acid (not just white vinegar, which might do the trick too, hmmm.) which will dissolve any phosphates or carbonates which could be causing the cloudiness.
Hope this helps."
