Popular questions
Is potassium nitrate soluble in water?
Yes—it's readily soluble in water (about 32 g per 100 g water at 20°C, increasing sharply with temperature) and only sparingly soluble in alcohol.
Why is potassium nitrate classified as an electrolyte?
Because it dissociates completely into potassium (K+) and nitrate (NO3−) ions in water, allowing the solution to conduct electricity as a strong electrolyte.
How to make potassium nitrate?
Industrial and food-grade potassium nitrate is made by neutralizing nitric acid with a potassium base (e.g., potassium hydroxide or carbonate) and then purifying/crystallizing; it should not be made at home, and food use requires regulated, food-grade material.
What does potassium nitrate do for teeth?
In desensitizing toothpastes, it helps reduce sensitivity by calming dental nerves (via potassium ions), with benefits building over several days to a few weeks of regular use.
What is potassium nitrate used for?
As E252, it's used in certain cured meats and cheeses as a preservative/curing aid under strict limits; outside food it’s used in fertilizers, some toothpastes for sensitivity, and pyrotechnics.
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.
