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 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.
