A buffer is 0.275 M in aqueous ammonia (NH3) and 0.310 M in ammonium nitrate, NH4NO3....
Determine the pH of a solution containing 0.125 M ammonia, NH3, and 0.275 M ammonium chloride, NH4Cl?
What is the pH of a 4.30×10-2 M aqueous solution of ammonium nitrate, NH4NO3 ?
A buffer solution contains 0.229 M ammonium chloride and 0.457 M ammonia. If 0.0568 moles of hydroiodic acid are added to 250 mL of this buffer, what is the pH of the resulting solution ? (Assume that the volume does not change upon adding hydroiodic acid) pH = Submit Answer Retry Entire Group 9 more group attempts remaining A buffer solution contains 0.443 M ammonium chloride and 0.314 M ammonia.

What is the pH of a 0.4647 M aqueous solution of ammonia? Kb (NH3) = 1.8x10-5
An ammonia buffer solution contains 0.24 M NH4+ and 0.21 M NH3. The pka of ammonium is 9.24. What is the pH of the buffer? Answer:
What is the pH of a 0.720 M aqueous solution of NH4NO3? The Kb for NH3 is 1.8 x 10-5.
Calculate the PH of a 0.36 M aqueous solution of NH4NO3. Kb of NH3= 1.8 x10^-5. Please show your work; I know how to do a normal problem but I am confused because the Kb is only for NH3, not the whole thing. Thanks!

A buffer solution consists of 0.00300 M ammonia (NH3) and 0.00500 M ammonium chloride (NH4Cl). What is the change in pH when 0.00100 moles of NaOH are added to one litre of the solution without any change in volume? The pKa of NH4+ is 9.24.
A buffer solution is prepared by combining 750.0 ml of 1.00 M of ammonia and 250 ml of 1.00 M ammonium chloride. What is the pH of the buffer? ( Ka of NH4+=5.6*10^-10, Kb of NH3= 1.8*10^-5)
