Given the following information: Buret contains .01 M EDTA; Both Solution A and B started with .042 g Calcium Magnesium Acetate; Solution A contains both magnesium and calcium; Solution B contains JUST magnesium (Ca was precipitated out); EDTA reacts with both Mg2+ and Ca2+ in a 1:1 ratio (if you use .0005 moles of EDTA, you have .0005 moles of metal ion). Titration of Solution A: Buret reading 1: 18.53 mL, Buret reading 2: 49.12 mL Titration of Solution B:...
Consider the titration of 50.0 mL of 0.20 M NH3 (Kb=1.8×10−5) with 0.20 M HNO3. Calculate the pH after addition of 50.0 mL of the titrant at 25 ∘C.
