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 the formula for magnesium phosphate?
For the food additive E343(i) monomagnesium phosphate, the formula is Mg(H2PO4)2 (often found as hydrates); the fully basic “magnesium phosphate” is Mg3(PO4)2.
What does monobasic mean?
Monobasic means only one acidic hydrogen per acid unit is replaced by a metal; in phosphates it refers to dihydrogen phosphate salts (H2PO4−), such as Mg(H2PO4)2.
What is magnesium ascorbyl phosphate?
It’s a stabilized vitamin C (ascorbic acid) derivative used mainly in cosmetics and skincare; it is different from the food additive magnesium phosphates (E343).
What is the molar mass of magnesium phosphate?
Anhydrous monomagnesium phosphate, Mg(H2PO4)2, is about 218.28 g/mol; the tribasic magnesium phosphate Mg3(PO4)2 is about 262.86 g/mol (hydrate forms will differ).
Why boric acid is monobasic acid?
In water, boric acid B(OH)3 acts as a Lewis acid that accepts one OH− to form B(OH)4−, effectively releasing only one proton equivalent, so it is monobasic.
