Some people might need more info. by the way.  Not everyone knows the formula for Citric Acid, and what the hell is the first equivalence point?

Vinegar: First of all, the kind of vinegar you get at the grocery store is about 95% water, but the vinegary part is acetic acid (also called ethanoic acid or methane carboxylic acid). The formula is written: CH3COOH.\n\ncoke: do u mean cocaine its C17H21NO4\n\nand i forgor about the nail polish remover its like this:\n\n"In chemistry, acetone (also known as propanone, dimethyl ketone, 2-propanone, propan-2-one and β-ketopropane) is the simplest representative of the ketones.\n\nAcetone is a colorless mobile flammable liquid with melting point at -95.4 °C and boiling point at 56.53 °C. It has a relative density of 0.819 (at 0 °C). It is readily soluble in water, ethanol, ether, etc., and itself serves as an important solvent. The most familiar household use of acetone is as the active ingredient in nail polish remover. Acetone is also used to make plastic, fibers, drugs, and other chemicals."\n\n\n\nis it good?!

Citric acid would probably be the easiest to come by.\nAsorbic acid (Vitamin C) is also anothe weak organic acid.

Well first you need to find the Ka of tartic acid: 10^-pKa = 1.05 x 10^-3.\n\nThen you create and ICE Table and solve for the Equilibrium concentration of Hydronium ions which gives you 0.02 M\n\nLastly, you find the pH which is -log [H3O+] = 1.6\n\nHope this helps

ag, aspirin is itself an ester, though. The para hydroxy group is esterified to reduce the acidity of the molecule.\n\nThe best way to determine it, in my book, would probably be by HPLC (High Performance liquid chromatography). We did an experiment in undergraduate analytical chemistry for this purpose ... to figure out ASA in Aspirin.\n\nThe main problem, analytically, with aspirin is that the ester group could react with the base. This would create an interference in your result, because you'll use more NaOH than you would otherwise and you'll think the aspirin concentration is higher than it actually is.\n\nIgnoring the ester, the way to recover the ASA is to pulverize (grind up) the aspirin tablet and dissolve it in chloroform (or dichloromethane). Then filter off the insoluble material and evaporate off the chloroform. You could then dissolve the resulting white powder in (pre-boiled) water and titrate with NaOH. The NaOH should be standardized with KHP.\n\nTo get rid of the ester, ag is correct. You'd need to react it with concentrated acid (or Lithium aluminium hydride, but I somehow doubt you have that lying around). Then you'd need to use TLC (thin layer chromatography) to make sure that all the ester was converted (by doing a comparison spot with salicylic acid). Then,  you'd need to remove the salicylic acid with a separation (chloroform or dichloromethane), evaporate it off, and titrate.\n\nAssuming all of that worked (organic procedures aren't truely analytical, all the time), you could then figure it out.

Look at their conjugate bases and whichever is more stable will have the weakest acid. PKA values are also easy to prove this becuase it is a realtion of the H+ content.

After cracking my head up and down , i got the answer.\nAfter mixing well all the ingredients keep it cool for 10 minutes.Use a litmus paper to do the test.\nRefer to the THEORY OF MIXING if it produces ethenal, then damm sure enough it is not ethenoic acid.\nGlad to help.
