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.
What foods have potassium bromate?
Primarily products made with 'bromated flour'—such as some breads, rolls, bagels, and pizza crusts—where it strengthens dough and improves rise. It’s banned in the EU/UK/Canada, and many U.S. bakers have phased it out.
What foods contain potassium bromate?
Where permitted (e.g., parts of the U.S.), certain commercial bakery items made with bromated high‑gluten flour may contain it, especially bread and pizza dough.
What brands use potassium bromate?
Usage varies by region and over time; in the U.S., some foodservice pizza/bread flours labeled 'bromated' use it, while many national retail brands and chains avoid it, and it’s banned in the EU/UK/Canada. Check labels for 'bromated flour' to confirm.
Does king arthur flour have potassium bromate?
No—King Arthur Baking Company states its flours are never bromated (and never bleached).
What is potassium bromate in?
It’s in bromated wheat flour used as a flour improver for yeast‑leavened doughs like bread, rolls, bagels, and pizza. Look for 'bromated flour' or E924a on ingredient lists where it’s allowed.
