Consider the following data on some weak acids and weak bases:acid baseKa name formula Kb name formula6.8x10-4 hydrofluoric acid HF 1.8x10-5 ammonia NH34.9x10-10 hydrocyanic acid HCN 1.7x10-9 pyridine C5H5NUse 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. solutiona) 0.1 M NaCN b) 0.1M NH4Brc) 0.1M KFd) 0.1M KBr

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

the correct answer would be b) volume versus temperature, because they are also directly proportional.
