9 août 2011 · 2–) sodium and chloride ions represent about 91 of all seawater ions chloride ions salinity can be determined from chloride concentration |
How do you measure chloride ion concentration?
The concentration of chloride ions is determined by subtracting the titration findings of the moles of silver ions that reacted with the thiocyanate from the total moles of silver nitrate added to the solution.
This method is used when the pH of the solution, after the sample has been prepared, is acidic.Calculation
Calculation
1%Cl = ((mL AgN03 for sample - mL AgN03 for blank) X NAgN03 X 3.545)/g sample.2%NaCl = %Cl (1.65)
