🔬 Chemistry Tips & Concepts
Understanding Normality
Normality (N) is the number of gram equivalents of solute per liter of solution. It's particularly useful in acid-base and redox reactions.
Percent Concentration
Percentage concentration can be weight/weight (% w/w), weight/volume (% w/v), or volume/volume (% v/v). This calculator uses % w/w.
Equivalent Weight
For acids, equivalent weight = molecular weight / H⁺ ions. For bases, it's molecular weight / OH⁻ ions. For salts, it depends on charge.
Density Matters
Solution density affects conversions between normality and percentage. More concentrated solutions often have higher densities.
Conversion Formula
% (w/w) = (Normality × Equivalent Weight) / (10 × Density). For dilute solutions, density ≈ 1 g/mL.
Safety First
Always handle chemical solutions with proper PPE. Know the hazards of your specific chemicals before working with them.
Note: This calculator provides estimates based on standard chemical properties. For precise laboratory work, always verify calculations and use exact density values for your specific solutions.
