Comparing E210 - Benzoic acid vs E336II - Dipotassium tartrate

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.

E336II - Dipotassium tartrate

Dipotassium tartrate (E336ii) is the potassium salt of tartaric acid that works mainly as an acidity regulator in foods and drinks. It helps keep pH stable, which protects flavor, color, and texture in products such as beverages, confections, and baked goods. It is also known as potassium tartrate or dipotassic tartrate.

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. How much potassium hydrogen tartrate in cream of tartar?

    Cream of tartar is essentially pure potassium hydrogen tartrate (E336i), typically >99%, and does not contain dipotassium tartrate (E336ii), which is a different salt.

  2. How to grow potassium sodium tartrate crystal?

    That’s Rochelle salt (potassium sodium tartrate), not E336ii; dipotassium tartrate (E336ii) crystals can be grown by making a hot saturated aqueous solution and letting it cool and evaporate slowly.

  3. How to prepare potassium sodium tartrate?

    Potassium sodium tartrate is a different compound; dipotassium tartrate (E336ii) is prepared by neutralizing tartaric acid with a potassium base (e.g., K2CO3 or KOH) and crystallizing the salt.

  4. Potassium hydrogen tartrate what is the ka?

    For potassium hydrogen tartrate (E336i), the relevant dissociation is tartaric acid’s second step: Ka2 ≈ 4×10^-5 at 25°C (pKa ≈ 4.3); dipotassium tartrate (E336ii) is fully neutralized and doesn’t have an acid dissociation constant.

  5. Potassium hydrogen tartrate what isthe ka?

    For potassium hydrogen tartrate (E336i), Ka2 ≈ 4×10^-5 at 25°C (pKa ≈ 4.3); E336ii (dipotassium tartrate) is a neutral salt and does not have a Ka.
