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.
Consider an aqueous solution which is .20m in potassium propanoate?
It will be basic, since propionate is the conjugate base of propionic acid (pKa ≈ 4.87); a 0.20 m aqueous solution has a pH of about 9.1.
Potassium propionate and aluminum powder make what?
They do not form a special or energetic compound under normal conditions—mixing them typically yields just a physical mixture with no reaction.
What is the decimal value for the hexadecimal number e283?
57987.
What is the fraction of association (α) for the following potassium propionate solutions?
In water, potassium propionate is essentially fully dissociated, so the fraction of association is ~0 (the degree of dissociation is ~1 at typical concentrations).
