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.
Is disodium phosphate bad for you?
Generally no—E339(ii) is an approved additive used at low levels; however, it contributes sodium and phosphate, so people with kidney disease or on phosphate‑restricted diets should limit it.
What is disodium phosphate in food?
It's the sodium salt Na2HPO4 (E339(ii)) used as an emulsifier, acidity regulator/buffer, stabilizer, sequestrant, humectant, and thickener.
What is disodium phosphate used for?
It emulsifies processed cheese, controls acidity, improves texture and moisture retention in dairy and meat products, and binds metal ions that can affect flavor and color.
Is disodium phosphate safe?
Yes—it's permitted by regulators (e.g., FDA GRAS; EU E339) and considered safe at typical food levels, though very high phosphate intakes are discouraged, especially for people with kidney problems.
What does disodium phosphate do?
It keeps mixtures smooth and stable, maintains pH, binds minerals to protect quality, and can help foods retain moisture and thickness.
