Choose the operation you need. Each tool explains what data you must enter, what the result means, and what mathematical assumptions it uses.
Do not use their results to mix sodium chlorite with HCl or any other acid. That reaction can dangerously release chlorine dioxide gas.
If you don't know which one to choose, read the phrase "Use it when..." on each card.
Calculate the milliliters per liter of water from the PPM of the CDS solution.
Use it when: you know the PPM and you need the result of the four protocols of the original calculator.
Open calculatorCalculate the volume of original CDS and water to obtain a lower final concentration.
Use it when: you know the initial ppm, the desired ppm and the final volume.
Open calculatorCalculate the approximate amount of water from the purity and mass of a powder product.
Use it when: The label indicates purity in %, you have a mass in grams and you are looking for a lower % m/m.
Open calculatorConverts between ppm, mg/L, g/L, % m/v and % m/m explaining when it is necessary to know the density.
Use it when: you have a correct concentration but you need to express it in another unit.
Open converterApply the dilution equation when both concentrations are expressed in mol/L.
Use it when: an already approved professional procedure specifies C1, C2 and final volume.
