WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. Image modified from " Water: Figure 7 ," by OpenStax College, Biology, CC BY 4.0. WebJan 30, 2024 · So, a hydrofluoric acid buffer would work best in a buffer range of around pH = 3.18. For the weak base ammonia (NH 3), the value of K b is 1.8x10-5, implying that the K a for the dissociation of its conjugate acid, NH 4 +, is K w /K b =10-14 /1.8x10-5 = 5.6x10-10. Thus, the pK a for NH 4 + = 9.25, so buffers using NH 4 + /NH 3 will work best ...
