Comparing E210 - Benzoic acid vs E938 - Argon

Overview

E210 - Benzoic acid

Benzoic acid (E210) is a preservative used to help keep acidic foods and drinks safe and fresh by slowing the growth of yeasts, molds, and some bacteria. It occurs naturally in small amounts in some berries and fermented foods, and is also made for food use under strict purity standards.

E938 - Argon

Argon (E938) is a colorless, odorless noble gas used in food packaging to protect products from air. It fills the headspace in packs and bottles to push out oxygen, helping keep flavors, aromas, and textures intact. Because argon is inert, it does not react with the food itself.

Popular questions

  1. 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.

  2. 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.

  3. Is benzoic acid a strong acid?

    No—it's a weak acid, with a pKa of about 4.2.

  4. What is the melting point of benzoic acid?

    About 122–123 °C (251–253 °F).

  5. 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.

  1. What element has 18 electrons?

    Argon (E938); a neutral argon atom has 18 electrons because its atomic number is 18.

  2. What element has 18 neutrons?

    The argon isotope argon‑36 (36Ar) has 18 neutrons (36 − 18 = 18).

  3. What element has 18 protons?

    Argon—its atomic number is 18, meaning it has 18 protons.

  4. What element has 17 protons and 18 neutrons?

    Chlorine‑35; that nucleus (17 protons, 18 neutrons) belongs to chlorine, not argon.

  5. Which element has 18 electrons?

    Argon (E938); a neutral argon atom carries 18 electrons.
