๐งช NaOH Normality Calculator
Professional solution preparation tool for sodium hydroxide (NaOH) - with purity correction and dilution calculator.
⚠️ CRITICAL SAFETY RULES
- ALWAYS add NaOH to water - NEVER add water to NaOH (causes violent boiling)
- Wear goggles, gloves, and lab coat
- Use fume hood or well-ventilated area
- Solution becomes very hot - let cool before adjusting volume
- Use distilled water only
Normality should be between 0.01 and 19 N
Purity must be between 1% and 100%
๐ Formulas Used:
• Preparation: Mass (g) = (Normality × 40 × Volume in Liters) ÷ (Purity/100)
• Dilution: C₁V₁ = C₂V₂
• Molecular weight of NaOH = 40 g/mol
• Preparation: Mass (g) = (Normality × 40 × Volume in Liters) ÷ (Purity/100)
• Dilution: C₁V₁ = C₂V₂
• Molecular weight of NaOH = 40 g/mol
