The hydrogen (H) atom in the carboxyl group (−COOH) in carboxylic acids such as acetic acid can be given off as an H+ ion (proton), giving them their acidic character. Acetic acid is a weak, effectively monoprotic acid in aqueous solution, with a pKa value of 4.8. A 1.0 M solution (about the concentration of domestic vinegar) has a pH of 2.4, indicating that merely 0.4% of the acetic acid molecules are dissociated.
Liquid acetic acid is a hydrophilic (polar) protic solvent, similar to ethanol and water. With a moderate dielectric constant of 6.2, it can dissolve not only polar compounds such as inorganic salts and sugars, but also non-polar compounds such as oils and elements such as sulfur and iodine. It readily mixes with many other polar and non-polar solvents such as water, chloroform, and hexane. This dissolving property and miscibility of acetic acid makes it a widely used industrial chemical.

Acetic acid is soluble in water because of its ability to form hydrogen bond with water through carboxyl group

basicaly acetic acid is CH3COOH, as u see the no. of carbon atoms is only 1 other than the COOH gp, so there is no steric hinderence or bulkiness on the other acetic acid molecule.
This results in the acid molecules to come a bit closer and the H-O-H also come closer to the acetic acid molecule .
Hence there is hydrogen bonding between the acid and water molecule as
..........O--H ::::: O------H ::::::
...... ../. . . . . . . ./
CH3C=O :::::: H
where the ::: represent hydrogen bonding,
Therefore acetic acid is highly soluble in water whereas higher acids are not due to steric hinderance..
Hope this answer helps u

acetic acid has a low pH value nearer to that of water.
hence it is soluble in water.

Because of its low density and hydrogenation abilities.
2007-01-22 20:42:07 · answer #8 · answered by Anonymous · 0⤊ 0⤋
this is due to the polar nature of the acid from the hydrogen ion
