Repeat the procedure in Exercise 65 for the titration of 25.0 mL of 0.100 M NH3 (Kb = 1.8 × 10-5) with 0.100 M HCl.
Answer to relevant QuestionsRepeat the procedure in Exercise 65 for the titration of 25.0 mL of 0.100 M pyridine (Kb = 1.7 × 10–9) with 0.100 M hydrochloric acid. Do not do the points at 24.9 mL and 25.1 mL. A certain indicator HIn has a pKa of 3.00 and a color change becomes visible when 7.00% of the indicator has been converted to In-. At what pH is this color change visible? The titration of Na2CO3 with HCl has the following qualitative profile: The Ksp for silver sulfate (Ag2SO4) is 1.2 × 10-5. Calculate the solubility of silver sulfate in each of the following. a. Water b. 0.10 M AgNO3 c. 0.20 M K2SO4 The overall formation constant for HgI42- is 1.0 × 1030. That is,
