Engineering calculator reviewed for preliminary design use · Last updated: March 2026
Perform dilution calculations using C₁V₁ = C₂V₂ and mixing calculations using mass balance. Calculate required stock solution volume for a target concentration, or find the resulting concentration when mixing two solutions. Apply to chemical preparation, cleaning solution setup, and process chemistry.
Dilution & Mixing Calculator
A concentration calculation tool for solution preparation, dilution, and mixing. Supports both dilution calculations (C₁V₁=C₂V₂) and two-stream mixing concentration calculations.
Dilution Calculation
C₁V₁ = C₂V₂ (solute before = solute after)
Calculate required dilution water volume
Determine concentrated solution needed for target concentration
Two-Stream Mixing
C_mix = (C₁V₁ + C₂V₂) / (V₁ + V₂)
Final concentration when mixing two solutions of different concentrations
Supports both mass-based and volume-based calculations
Applications
Cleaning and disinfectant solution preparation
Chemical dilution and blending
Process stream concentration control
Frequently Asked Questions
Does C₁V₁ = C₂V₂ work for all concentrations?
This formula works well for dilute solutions where mixing does not significantly change the total volume. For concentrated solutions or solutions with large density differences, volume changes on mixing must be accounted for.
Can I use this for mixing acids or other reactive solutions?
Only if the solutions do not react or generate significant heat. For acid dilution (especially concentrated sulfuric acid), heat of dilution is substantial and can cause dangerous temperature rise. Follow specific safety procedures.
