You have been tasked with making a 1.50 L buffer solution with 0.250 M in HF and 0.250 M in NaF so all of your experiments will have a constant pH value. Under no circumstances can your pH leave the range of 3.2-3.7. A clumsy professor, Dr. Urkel, walks by and accidentally spills 0.100 moles of solid NaOH into your solution. Will your buffer be able to withstand the addition and still stay in the range? Calculate the new pH of the solution after the addition
