Analisis kloridadlm air dg alat potensiometer, Titrino/Titroprocessor

Alat yg digunakan
Potentiometer = 751 GPD Titrino / Titroprocessor
Electrodes = 6.0430.100 Ag Titrode amalgamated; input 1

Reagents
c(AgNO3) = 0.01 mol/L; D0

Sample
100 mL tap water
0.5 mL c(HNO3) = 2 mol/L

Remarks
. Calculations:

Chloride=EP1*C01*C02*C03/C00;2;ppm

Chloride = fraction of chloride in ppm
C01 = concentration of titrating agent (0.01 mol/L)
C02 = molecular mass of Cl- (35.45 g/mol)
C03 = factor for ppm (1000)

. Answer

Chloride = 1.533 x 0.01 x 35.45 x 1000 / 100 = 5.43 ppm

EP1 = 1.533 mL
C00 = 100 mL
