. What is the purpose of the Ba(NO3)2 ? 2. What percent of Agl remains unprecipitated when the first amount of AgCl starts to precipitate? 3. What effect would the presence of 1 M ammonia have on the above titration? Be specific in your answer. Indicate how you would experimentally evaluate the equilibrium constant for the silver-amine complex. 4. Explain why you do not need to know the half-cell potential for the reference electrode in order to calculate the Ksp for AgCl and AgI. 5. Compare the methods that you used to determine the endpoint

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
