The solubility of AgI in water is much less than that of AgCl in water.
The solubility product of AgCl = [Ag+][Cl-] = 1.8×10-10
Where [Ag+] = [Cl-]
Therefore, [Ag+] = (1.8×10-10)1/2 = 1.34×10-5 M
Now, the solubility product of AgI = [Ag+][I-]
i.e. 8.3×10-17 = 1.34×10-5 [I-]
i.e. [I-] = 6.2×10-12 M
Hence, even though I- is in low concentrations, it will severely interfere with the Cl- electrode immersed in the corresponding solution and here, the Cl- electrode forms the corresponding I- electrode.
Add Answer to:
Given Ksp(AgCl) = 1.8x 10-10 and Ksp(Ag) = 8.3x10-17, provide a plausible reason why I would severely interfere with th...

1. Without doing a calculation, predict which of these compounds has the greatest molar solubility in water: AgCI (Ksp=1.8x10-10), AgBr (Ksp 5.0x10-13), or AgI (Ksp=8.3x10-17). Optional Answers: 1. AgI is the most soluble of the three. 2. AgBr is the most soluble of the three. 3. AgCl is the most soluble of the three 4. All of the compounds are totally insoluble based on their...

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
