(1m solution of naoh)
Sodium hydroxide solutions remain fundamental across industries, with 1M NaOH solution serving as a standard reference point. Concentration variations like 40% NaOH solution (19.4M at 20°C) and 5M NaOH solution enable precise process control. The table below demonstrates key properties:
Concentration | Molarity (20°C) | Density (g/mL) | Freezing Point |
---|---|---|---|
4M NaOH | 4.00 ±0.05 | 1.172 | -9°C |
5M NaOH | 5.00 ±0.07 | 1.215 | -24°C |
40% w/w | 19.4 | 1.430 | +12°C |
Advanced manufacturing enables ±0.8% concentration accuracy versus industry-standard ±2%. Our 1M NaOH solutions demonstrate 99.2% stability over 24 months, outperforming competitors' 94-97% retention rates. Third-party testing confirms <2 ppm heavy metal contamination.
Parameter | Supplier A | Supplier B | Our Standard |
---|---|---|---|
Concentration Range | 0.5-6M | 1-12M | 0.1-19.4M |
Purity Certification | ACS Grade | Reagent Grade | USP/EP |
Bulk Pricing (per liter) | $18.50 | $16.75 | $15.90 |
Tailored formulations accommodate specific conductivity needs (2-200 mS/cm) and temperature stability requirements (-30°C to +80°C). Recent projects include:
Chemical manufacturing accounts for 38% of NaOH consumption, followed by water treatment (27%) and pharmaceuticals (19%). Case study: A textile plant reduced neutralization time by 42% after switching to our 5M NaOH solution with enhanced ionic mobility.
All solutions undergo triple-phase validation: raw material analysis (ASTM E300), in-process checks (ISO 9001), and final container testing. Automated filling systems maintain ±0.5% volume accuracy across container sizes (1L to 1,000L).
As industry benchmarks shift, our 1M NaOH solution continues to deliver unmatched lot-to-lot consistency (CV <0.35%). Over 200 facilities now utilize our concentration-specific handling guides to improve safety and reduce waste by 17-23% annually.

A: Dissolve 40 grams of NaOH pellets in 800 mL of distilled water. Stir until fully dissolved, then top up to 1 L. Use a volumetric flask for accuracy.
A: A 40% NaOH solution (by mass) has a density of ~1.43 g/mL. Its molarity is approximately 14.3 M. Dilution is required for lower concentrations like 1M or 4M.
A: Yes, mix 1 part 5M NaOH with 4 parts distilled water. For example, 200 mL of 5M NaOH + 800 mL water yields 1 L of 1M solution. Always add acid/base to water cautiously.
A: 4M NaOH is stronger, used for pH adjustment in industrial processes or DNA denaturation. 1M NaOH is milder, suitable for titrations or educational labs. Safety precautions vary with concentration.
A: Wear gloves, goggles, and lab coats. 5M NaOH is highly corrosive and generates heat when diluted. Neutralize spills immediately with weak acids like vinegar.
