Chemical Dilution Calc

Need 500mL of 10% from a 70% stock - how much water? Solves any unknown in C1V1=C2V2, dilution ratio and exact water-to-add. $1.99 one-time, no login.

Need to dilute a stock solution but keep fumbling the C1V1=C2V2 math? Chemical Dilution Calc solves for any unknown variable instantly — no more manual algebra in the lab or treatment plant.

Enter any three values (initial concentration, initial volume, final concentration, final volume) and get the missing fourth. See dilution ratio and exact water-to-add volume at a glance.

SOLVE FOR ANY VARIABLE:

• C1 — initial (stock) concentration
• V1 — initial volume needed
• C2 — final (target) concentration
• V2 — final total volume

INSTANT RESULTS:

• Missing variable calculated in real time
• Dilution ratio displayed (e.g. 10:1)
• Water to add shown in mL
• Works with any concentration unit (%, ppm, molarity)

WHO IT IS FOR:

• Laboratory technicians preparing reagent solutions
• Water treatment operators mixing chemical feeds
• Pharmacy compounding staff
• QC analysts running serial dilutions
• Agricultural chemists mixing spray solutions

Simple, fast, accurate. Enter three knowns, get the fourth. Works completely offline — no internet required.
