determine the concentration of chlorine (CCl) in dry gas at standard conditions using titration data

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)
