At 25°C and 1.00 atm pressure, one liter of ammonia is bubbled into 725 mL of water. Assume that all the ammonia dissolves and the volume of the solution is the volume of the water. A 50 mL portion of the prepared solution is titrated with 0.2193 M HNO3. Calculate the pH of the solution....(a) before titration(b) halfway to the equivalence point(c) at the equivalence point
