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.
Is potassium hydroxide a strong base?
Yes—potassium hydroxide (KOH) is a prototypical strong base that fully dissociates in water and is highly caustic in concentrated form.
What is potassium hydroxide used for?
In foods (E525) it’s used as an acidity/pH regulator and processing aid, e.g., for lye peeling of fruits and vegetables, curing olives, and in some cocoa and caramel color processing.
Is potassium hydroxide safe?
Yes—at permitted food-use levels it’s considered safe (GRAS in the U.S. and authorized in the EU); concentrated solutions are corrosive and must be handled carefully.
What is the formula for potassium hydroxide?
KOH.
