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.
What is calcium gluconate used for?
In foods (E578) it acts as a sequestrant and calcium source to improve stability and fortify products; medically it’s used to treat hypocalcemia, protect the heart in severe hyperkalemia, counter magnesium toxicity, and manage hydrofluoric acid exposure.
How does calcium gluconate treat hyperkalemia?
It doesn’t lower potassium; it stabilizes cardiac cell membranes by increasing extracellular calcium, reducing excitability and the risk of life‑threatening arrhythmias within minutes (effect ~30–60 minutes).
What does calcium gluconate do?
As a food additive it binds metal ions to prevent quality loss and supplies calcium; as a medicine it replaces calcium, stabilizes the myocardium in hyperkalemia, and treats hypocalcemia and magnesium toxicity.
What is calcium gluconate the antidote for?
It is an antidote for hydrofluoric acid exposure (topical/systemic) and for magnesium toxicity; it may also be used as an adjunct in calcium channel blocker overdose.
How to administer calcium gluconate injection?
By healthcare professionals only as slow IV push or infusion (not IM or subcutaneous due to tissue damage); a common adult dose for cardioprotection/hypocalcemia is 10 mL of 10% solution (1 g) over 5–10 minutes with ECG monitoring, repeat as needed. Avoid mixing with bicarbonate or phosphate solutions and monitor for extravasation.
