Consider the following data on some weak acids and weak bases:
acid base
ka name formula kb name formula
6.8x10-4 hydrofluoric acid hf 1.8x10-5 ammonia nh3
4.9x10-10 hydrocyanic acid hcn 1.7x10-9 pyridine c5h5n
use this data to rank the following solutions in order of increasing ph. in other words, select a '1' next to the solution that will have the lowest ph, a '2' next to the solution that will have the next lowest ph, and so on.
