Gen Chem Exam 3 Questions And Answers 2024 (A Graded Solution)

Gen Chem Exam 3 Questions And Answers 2024 (A Graded Solution) What compounds are soluble? - ANS-Group 1 ions and all nitrates (NO3-) Calculate the solubility of Sr(SO4-)2 How would you approach this problem? - ANS-First, write out the Ksp for this specific compound. So, Ksp = [Sr2+][SO42-]^2, Then, ICE table, +s and +2s, and that = 4s^3. That equals given Ksp How do you figure out if a precipitate will form? - ANS-Calculate Qsp. This is done by multiplying the given ion concentrations If Qsp<Ksp, then no precipitate will form If Qsp>Ksp, then a precipitate will form If Qsp = Ksp, then precipitate starts to form How do you know which is oxidized and reduced? - ANS-It's being reduced if you're adding electrons to it on the left side of the equation How do you know which ion will precipitate first? - ANS...
