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 nitrosyl chloride polar?
Yes—NOCl is a polar molecule due to its bent geometry at nitrogen and the differing electronegativities of O and Cl, which produce a net dipole.
(b) in which species (no2cl or no3-) are the n-o bond(s) longer? nitrosyl chloride nitrate ion?
Longer in nitrate (NO3−): its N–O bonds have lower bond order (~1.33) than the N=O double bond in nitrosyl chloride, so they are longer.
How is nitrosyl chloride used?
As the additive E919 it was historically used as a flour treatment/bleaching agent, but this use is now largely discontinued and not authorized in the EU; today it is mainly an industrial chlorinating/nitrosating reagent rather than a common food additive.
Nitrosyl chloride nocl decomposes to nitric oxide and chlorine when heated answer l?
Yes—on heating, 2 NOCl → 2 NO + Cl2, and the decomposition is promoted by heat and light.
Question 6 what is the "axe" description of the nitrosyl chloride molecule?
AX2E1 at the nitrogen center (two bonded atoms and one lone pair), giving trigonal planar electron geometry and a bent molecular shape.
