Chem(check my work, mass percent acetic acid)
I do believe this is the right annswer (.11g Acetic Acid present). When you you use the above equation for the mass percent of acetic acid (g CH3COOH/g sample) you end up with 4.3% Acetic Acid. That is a normal concentration of acetic acid [I looked at other sites for ...

I am not exactly sure what you mean by "what is the explanation of the pure acetic acid?" Acetic acid or ethanoic acid is clear colourless liquid. Pure acetic acid is sometimes called glacial acetic acid because it forms ice like crystals when it solidifies at abut 16C.

chemistry - synthesis of aspirin
wait, i misunderstand. You stated that if there's no H2O present then salicylic acid is the limiting reagent. Therefore salicylic acid number of moles is the same as the number of moles of acetic acid???? If this is so, then the mass of acetic acid would also be 2.005 g, right?

Ice table ? I haven't heard of that term in awhile. Well since acetic acid is a weak acid and NaOH is a strong base... 120ml 0.15M acetic acid 30ml 0.2M NaOH -You need Ka for the weak acid. (for acetic acid Ka= 1.8x10^-5) steps: 1. Determine if moles H+ or moles OH- is in ...

1. acetic acid will donate a proton. Acetylene will also but if you can pick only one answer go with acetic acid. 2. What do you think, and why, for 2 and 3?

You want to prepare a pH=4.50 buffer using sodium acetate and glacial acetic acid. You have on hand 300 mL of 0.100 M sodium acetate. How many grams of glacial (water free) acetic acid should you add to prepare the buffer? (Ka of acetic acid is 1.8e-5 at: 25 degrees Celsius)

The acid is acetic acid. Either in your problem or in your text the Ka should be listed as close to 1.8E-5 which is a pKa of 4.74 (pKa = -log Ka). Use the value in your text or notes, not the one I used. The base is acetate. The acid is acetic acid in the HH equation.
