Popular questions
Is ascorbic acid bad for you?
No—ascorbic acid (vitamin C) is considered safe at typical food levels and is essential for health; it’s GRAS in the U.S. and approved in the EU. Very high supplemental doses can cause gastrointestinal upset and, in susceptible people, increase kidney stone risk.
Can dogs have ascorbic acid?
Yes, small amounts in foods are safe, but dogs synthesize their own vitamin C and usually don’t need supplements. High doses may cause diarrhea, so consult a veterinarian before supplementing.
What is ascorbic acid made from?
Commercial ascorbic acid is typically made from glucose (often derived from corn, wheat, or cassava) that’s converted via microbial fermentation and chemical steps into L‑ascorbic acid.
How is ascorbic acid made?
Industrially, D‑glucose is converted to 2‑keto‑L‑gulonic acid by fermentation (or via the older Reichstein process: glucose → sorbitol → L‑sorbose → 2‑KGA) and then chemically cyclized to ascorbic acid. Modern methods use two-step fermentation to improve efficiency.
Is ascorbic acid the same as citric acid?
No—ascorbic acid (E300) is vitamin C and an antioxidant, while citric acid (E330) is a different compound mainly used as an acidulant and does not provide vitamin C.
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).
