Chemical Concentration Adjustment Calculator
Chemical Concentration Adjustment Calculator: calculate addition with consistent units and explicit assumptions.
Inputs
kg
wt%
wt%
wt%
Results
- Addition required
- 12.5 kg
- Final batch mass
- 112.5 kg
- Target concentration
- 20 wt%
Formula
Addition = batch × (target−current)/(feed−target)
Blend feed 1 = final mass × (target−feed 2)/(feed 1−feed 2)
Dilution: Cstock × Vstock = Ctarget × Vfinal
Assumptions & limits
- Mass fractions are wt%, not volume%. Components are conserved; no reaction, evaporation or precipitation.
- Planning calculation only: verify assays, solubility, heat release and handling with a qualified chemist.
- Dilution mode requires matching volume concentration units (e.g. mol/L or mg/L); wt% cannot be directly used with volume.
Worked example
For the example inputs: Addition required = 12.5 kg; Final batch mass = 112.5 kg; Target concentration = 20 wt%.
Addition = batch × (target−current)/(feed−target)
