Order these chemical species by increasing of an aqueous solution of each. That is, imagine making an solution of each species. Select next to the species that makes the solution with the lowest . Select next to the species that makes the solution with the next higher , and so on. Notice that some of the rankings have been filled in for you already. Also notice that water is on the list. For that particular case, just compare the of pure water to the of the other solutions. Note for advanced students: for all charged species, you may assume the necessary counterions act as neither acids nor bases. species relative pH of 0.1M aqueous solution OH− (Choose one) HF (Choose one) IO3− (Choose one) F− 6 H2O 4 HIO3 1 (lowest) NO2− (Choose one) HNO2 3
