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.
Ferric ammonium citrate green rock hard, how to reconstitute?
It cakes but remains highly water‑soluble: break up the mass and dissolve in distilled/deionized water with stirring; gentle warming (up to ~40–50°C) can help, then filter if needed and store airtight with a desiccant to prevent re‑hardening.
Ferric ammonium citrate rock hard, how to reconstitute?
Crush to increase surface area and dissolve in deionized water under vigorous stirring; mild heat aids dissolution—avoid boiling—and store the solid or solution tightly sealed to limit moisture cycling and caking.
Ferric ammonium citrate what is?
A synthetic, water‑soluble iron(III) complex of citrate with ammonium (E381), used in foods where permitted mainly as an iron fortificant and acidity regulator.
How cells uptake ferric ammonium citrate?
In cell culture it provides non‑transferrin‑bound Fe3+ that is reduced at the membrane and transported primarily via DMT1 as Fe2+; uptake can vary by cell type and conditions.
How is ferric ammonium citrate?
It is a very water‑soluble green or brown solid used in foods (E381) where allowed as an iron source and acidity regulator; typical use levels follow good manufacturing practice and applicable regulations.
