Popular questions
Is benzoic acid soluble in water?
Only sparingly—about 3 g per liter at room temperature; its solubility increases in hot water and it dissolves readily in many organic solvents.
Is benzoic acid polar?
It has a polar carboxyl group but a nonpolar aromatic ring, so overall it’s only weakly polar; its benzoate salt is much more polar and water‑soluble.
Is benzoic acid a strong acid?
No—it's a weak acid, with a pKa of about 4.2.
What is the melting point of benzoic acid?
About 122–123 °C (251–253 °F).
Is benzoic acid bad for you?
At approved food levels it’s considered safe, with an ADI of 0–5 mg/kg body weight/day; some people may experience irritation or hypersensitivity, and benzene formation in certain acidic drinks is monitored and kept very low.
What does sodium dehydroacetate do?
It acts as a preservative, inhibiting the growth of molds, yeasts, and some bacteria to extend shelf life.
What is sodium dehydroacetate derived from?
It is the sodium salt of dehydroacetic acid, made synthetically by neutralizing dehydroacetic acid with sodium hydroxide.
What is the e number of sodium dehydroacetate?
Its E-number is E266.
