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 potassium alum safe?
Yes—when used within legal limits in foods, potassium alum (E522) is permitted for limited uses and considered safe; nonetheless, total aluminum intake should stay below EFSA’s tolerable weekly intake of 1 mg/kg body weight, and people with kidney disease should be cautious.
Does potassium alum contain aluminum?
Yes; it’s a double sulfate salt (KAl(SO4)2·12H2O) that contains trivalent aluminum.
Is potassium alum aluminum?
No; it isn’t elemental aluminum but a sulfate salt that contains aluminum ions.
Is potassium alum bad for you?
Not at the small amounts allowed in foods; excessive aluminum exposure can be a concern—especially for people with impaired kidney function—so uses and levels are restricted.
Is potassium alum the same as aluminum?
No; potassium alum (aluminum potassium sulfate) is a compound containing aluminum, not the same as pure aluminum metal.
