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. Buying caustic soda, how to use it to dissolve alum?

    E521 (aluminium sodium sulphate, “alum”) is readily soluble in plain water; you don’t need caustic soda, and mixing it with sodium hydroxide can cause an alkaline reaction and is not appropriate for food use.

  2. Cinema modeoff how to repair a 12 volt battery for under 5 dollars using alum and baking soda?

    E521 is a food-grade leavening acid used in baking powders and water treatment, not intended for battery repair; using “alum” in lead–acid batteries is unsafe and not recommended.

  3. Dell dimension e521 how remove a firewire pci card?

    E521 here refers to aluminium sodium sulphate, a food additive used as an acid in baking powder, and is unrelated to computer hardware.

  4. Dell dimension e521 when to replace battery?

    E521 is the EU code for aluminium sodium sulphate, a food additive, not a device model, so it has nothing to do with batteries.

  5. E521 how to know if a comic is updated?

    E521 denotes aluminium sodium sulphate in the EU additives list and isn’t related to comics or apps; I can help with its food uses or safety if needed.
