Popular questions
What is e262 in food?
E262 is sodium acetates (sodium acetate and sodium diacetate), used as a preservative and acidity regulator to control pH and inhibit microbial growth.
What is sodium acetates formula?
Sodium acetate is CH3COONa (anhydrous) or CH3COONa·3H2O (trihydrate); sodium diacetate (E262(ii)) is CH3COONa·CH3COOH.
What is sodium acetates symbol?
Chemically it’s written as CH3COONa (often abbreviated NaOAc); on food labels the code is E262.
Where is area cod e262?
E262 isn’t an area code—it’s the EU food additive number for sodium acetates shown on ingredient lists.
Why are sodium bicarbonate and sidium acetates?
Both are sodium salts of weak acids used in foods: sodium bicarbonate acts as a leavening agent/acid neutralizer, while sodium acetates preserve foods and help regulate acidity.
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.
