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.
How to calculate calcium iodate solubility in potassium iodate solution?
Use the dissolution Ca(IO3)2(s) ⇌ Ca2+ + 2 IO3− and Ksp = [Ca2+][IO3−]^2; with initial iodate C from KIO3, solve Ksp = s(C + 2s)^2 for molar solubility s (if C ≫ s, s ≈ Ksp/C^2).
How to calculate solubility of calcium iodate?
In pure water, let s be molar solubility: Ksp = s(2s)^2 = 4s^3, so s = (Ksp/4)^(1/3); convert to g/L by multiplying s by the molar mass of Ca(IO3)2.
How to calculate the concentration of iodate from calcium iodate in 0.1 kio3?
With [IO3−]0 = 0.1 M from KIO3, the iodate contributed by dissolving Ca(IO3)2 is 2s where s solves Ksp = s(0.1 + 2s)^2 (if 0.1 ≫ s, [IO3−] from Ca(IO3)2 ≈ 2Ksp/(0.1)^2).
How to calculate the concentration of iodate from calcium iodate in pure water?
For Ca(IO3)2 in water, [IO3−] = 2s with s = (Ksp/4)^(1/3), so [IO3−] = 2(Ksp/4)^(1/3) assuming activities ≈ concentrations.
How to find molar solubility of calcium iodate?
Write Ksp = [Ca2+][IO3−]^2; in pure water s = (Ksp/4)^(1/3), and in a solution with iodate C (common ion) s is given by Ksp = s(C + 2s)^2 ≈ Ksp/C^2 when C ≫ s.
