Popular questions
Is benzoic acid soluble in water?
Only sparingly—about 3 g per liter at room temperature; its solubility increases in hot water and it dissolves readily in many organic solvents.
Is benzoic acid polar?
It has a polar carboxyl group but a nonpolar aromatic ring, so overall it’s only weakly polar; its benzoate salt is much more polar and water‑soluble.
Is benzoic acid a strong acid?
No—it's a weak acid, with a pKa of about 4.2.
What is the melting point of benzoic acid?
About 122–123 °C (251–253 °F).
Is benzoic acid bad for you?
At approved food levels it’s considered safe, with an ADI of 0–5 mg/kg body weight/day; some people may experience irritation or hypersensitivity, and benzene formation in certain acidic drinks is monitored and kept very low.
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.
