Chlorine Concentration online

Chlorine Concentration (CCl)

Use this calculator to determine the concentration of chlorine (CCl) in dry gas at standard conditions using titration data:

Formula:

CCl = [35.5 × (Vt - Vb) × M × Vsoln] / (Vstd × Va)

V_t – Volume of titrant used for test (ml):


V_b – Volume of titrant used for blank (ml):


M – Molarity of sodium thiosulphate solution (mol/L):


V_soln – Total volume of KI solution (ml):


V_a – Volume of aliquot (ml):


V_std – Volume of dry gas (m³):

Abbreviations & Notes:

• CCl – Chlorine concentration in mg/m³ (standard, dry)
• V_t – Volume of titrant for potassium iodide aliquot (ml)
• V_b – Volume of titrant for blank (ml)
• M – Molarity of sodium thiosulphate (mol/L)
• V_soln – Total volume of potassium iodide solution (ml)
• V_a – Aliquot volume (ml)
• V_std – Volume of dry gas sample (m³)
• k – Conversion factor: 35.5 mg·L/mol·ml (for Cl₂)
