Popular questions
How many grams of potassium nitrite are present in 1.48 moles?
Approximately 126 g, using KNO2 molar mass ≈85.1 g/mol (1.48 mol × 85.1 g/mol).
How many grams of potassium nitrite exist in 143 ml of a 2.80 m solution?
If 2.80 M (mol/L) was intended, about 34.1 g (0.143 L × 2.80 mol/L × 85.1 g/mol); if 2.80 m (mol/kg solvent), you need the solvent mass or solution density to determine grams.
How many moles of potassium nitrite kno3 are present in a sample with a mass of 85.2g.?
KNO2 and KNO3 are different: 85.2 g is about 1.00 mol of KNO2 (M≈85.1 g/mol) or about 0.843 mol of KNO3 (M≈101.1 g/mol)—clarify which compound you have.
How to balance potassium nitrite?
Balance equations by equalizing K, N, and O atoms on both sides; for example, the oxidation is 2 KNO2 + O2 → 2 KNO3, which is balanced as written.
How to make a storm glass without potassium nitrite or ammonium chloride?
Use a salt‑free formulation: dissolve camphor in ethanol and add distilled water (e.g., ~10 g camphor in 40 mL ethanol plus ~35–40 mL water), seal tightly; it will form temperature‑responsive crystals, but it’s not a true weather predictor and avoids toxic nitrite salts.
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.
