Popular questions
Is acetic acid a strong acid?
No—acetic acid (E260) is a weak acid in water (pKa ≈ 4.76), though concentrated (glacial) acetic acid is corrosive.
Is vinegar acetic acid?
Vinegar is a solution of acetic acid in water (typically about 4–8% acetic acid by volume), not pure acetic acid.
What is acetic acid used for?
In foods, E260 is used as an acidity regulator, preservative, and flavoring (e.g., pickling, sauces); industrially it’s a precursor to vinyl acetate and cellulose acetate and is used in descaling/cleaning.
Which statement describes the acid found in vinegar acetic acid?
It is a weak organic acid (ethanoic acid, CH3COOH) that gives vinegar its sour taste and antimicrobial effect; food-grade vinegar contains at least about 4% acetic acid by volume.
Is acetic acid polar?
Yes—acetic acid is a polar, hydrogen-bonding (protic) molecule due to its carboxyl group, and it mixes well with water and many polar solvents.
How to prepare ammonium acetate buffer solution?
Dissolve ammonium acetate in water to the desired concentration (e.g., 1 M: about 77 g per liter), then adjust pH to your target with acetic acid (to lower) or ammonia (to raise) and dilute to volume. Use food-/pharma-grade materials and verify pH after mixing.
Is ammonium acetate soluble in water?
Yes—it's highly soluble in water.
Ammonium acetate dissolves into what ions?
It dissociates into ammonium (NH4+) and acetate (CH3COO−) ions.
Ammonium acetate in what products contain?
It may appear in some pickled products, sauces, and baked goods as an acidity regulator/buffer (E264). It’s relatively uncommon and is often replaced by sodium or potassium acetates.
Consider the reaction when aqueous solutions of ammonium acetate and sodium phosphate are combined.?
All ions remain in solution (no precipitate), leaving NH4+, CH3COO−, Na+, and phosphate species in equilibrium. In a sufficiently basic phosphate solution, some NH4+ can convert to ammonia, making the mixture slightly basic and possibly giving a mild ammonia odor.
