Analisis Klorida di dlm air dg alat Titrino / Titroprocessor

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

Reagents
c(AgNO3) = 0.1 mol/L; D0

Sample
5 mL c(NaCl) = 0.1 mol/L
2 mL c(HNO3) = 2 mol/L
40 mL dist. Water

Remarks
· Calculations:

Chloride=EP1*C01*C02*C03/C00;2;%
NaCl=EP1*C01*C04/C00;2;g/l

Chloride = content of chloride in %
NaCl = content of NaCl in g/L
C01 = concentration of titrating agent (0.1 mol/L)
C02 = molecular mass of Cl- (35.45 g/mol)
C03 = factor for % (0.1)
C04 = molecular mass of NaCl (58.44)
· Select the appropriate formula. The other may be deleted. Or change the formula according to your application.

. Answer

Chloride=4.969x0.1x35.45x0.1/5=0.35%
NaCl=4.969x0.1x58.44/5=5.81 g/L

EP1=4.969 mL
C00=5.000 mL
