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 iodate dangerous?
At permitted food-use levels it’s considered safe, but it’s a strong oxidizer and excessive iodine intake can disturb thyroid function (especially in people with thyroid disease, infants, or during pregnancy). As a pure chemical it can irritate eyes/skin and should be handled with care.
Why is potassium iodate banned?
In the EU/UK it’s not authorized as a food additive (flour treatment agent) due to safety concerns about excess iodine exposure and lack of technological need; however, some countries still allow limited uses such as salt iodization. Regulations vary by country.
What is potassium iodate used for?
It’s used as an oxidizing flour improver/dough conditioner in some countries and as a stable iodine source for iodizing table salt.
How does sodium bisulfite and potassium iodate react to make iodine reaction with starch equations?
In acid, bisulfite first reduces iodate to iodide: IO3− + 3 HSO3− → I− + 3 HSO4−; once bisulfite is consumed, iodate oxidizes iodide to iodine: IO3− + 5 I− + 6 H+ → 3 I2 + 3 H2O; iodine then forms I3− with I− (I2 + I− → I3−), which gives the blue starch–iodine complex.
How much of solid kio3 do you need to make 25.00ml of a 0.20m potassium iodate solution? 1.07 g?
About 1.07 g KIO3 (0.02500 L × 0.200 mol/L = 0.00500 mol; molar mass ≈ 214 g/mol; mass ≈ 1.07 g).
