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.
How to flash e366 to e347?
You can’t “flash” one E-number to another: E366 (potassium fumarate) and E347 are different additives; switching would require reformulating the product, not any kind of update.
How to order potassium fumarate?
Purchase from food-ingredient suppliers or chemical distributors and specify food/FCC or EU food-grade E366; request a certificate of analysis and confirm it’s permitted for your intended use locally.
How to reset e366?
There’s nothing to reset—E366 is simply the E-number for potassium fumarate, an ingredient, not a device or error code.
What is low e366?
There’s no standard “low E366” label; when used, potassium fumarate is typically added at low levels as an acidity regulator.
What is the e number of potassium fumarate?
E366.
