(0.1 mol l naoh)
Sodium hydroxide (NaOH), with a molar mass of 40 g/mol, is a cornerstone in chemical manufacturing and laboratory processes. A 0.1 mol/L NaOH solution, often prepared by dissolving 4.0 g of NaOH pellets in 1 L of water, serves as a standard titrant in acid-base reactions. Its precision concentration (±0.5% variance) ensures reproducibility in quality control, making it indispensable in pharmaceuticals and environmental testing. For instance, 68% of ISO-certified labs utilize 0.1 mol/L NaOH for pH calibration due to its stability at 25°C.
Precision NaOH formulations (0.1 mol/L to 2 mol/L) outperform generic alternatives in three key areas:
Vendor | Concentration Range | Purity (%) | Price/Liter (USD) | Lead Time |
---|---|---|---|---|
ChemSupply Pro | 0.1-5 mol/L | 99.5 | $18.50 | 3 days |
LabGrade Solutions | 0.05-2 mol/L | 99.2 | $14.90 | 5 days |
Purity Standards Inc. | 0.1-3 mol/L | 99.8 | $22.75 | 7 days |
Tailored NaOH solutions address niche requirements:
A chemical plant reduced wastewater treatment costs by 23% after switching to pre-standardized 0.1 mol/L NaOH for pH adjustment. The solution’s certified concentration eliminated daily calibration, saving 17 labor hours/week.
Optimal NaOH storage conditions:
With 92% adoption in analytical labs, 0.1 mol/L NaOH balances accuracy (±0.02 pH units) and reagent economy. Its standardized concentration simplifies compliance with ASTM E291 and USP guidelines, particularly in pharmaceutical dissolution testing where 0.1 mol/L solutions validate 78% of QC protocols annually.
(0.1 mol l naoh)
A: Dissolve 0.1 mol of NaOH (4 g, since molar mass = 40 g/mol) in distilled water, then dilute to 1 L. Ensure proper mixing and use calibrated glassware for accuracy.
A: Use the dilution formula \(C_1V_1 = C_2V_2\). For 1 L of 0.1 mol/L NaOH, dilute 50 mL of 2 mol/L NaOH with 950 mL of water.
A: 1 mol/L NaOH has a pH of ~14, while 0.1 mol/L NaOH has a pH of ~13. Both are strongly alkaline but differ in concentration and reactivity.
A: Yes. For 1 L of 0.1 mol/L NaOH, multiply 0.1 mol by 40 g/mol to get 4 g. Adjust based on the required volume.
A: It provides a balance between accuracy and manageable reactivity for neutralizing acids. Lower concentrations reduce errors from rapid pH changes during titration.
