Order these chemical species by increasing pH of an 0.1M aqueoussolution of each. That is, imagine making an 0.1M solution of eachspecies. Select 1 next to the species that makes the solution withthe lowest pH. Select 2 next to the species that makes the solutionwith the next higher pH, and so on. Notice that some of therankings have been filled in for you already. Also notice thatwater is on the list. For that particular case, just compare the pHof pure water to the pH of the other solutions. Note for advancedstudents: for all charged species, you may assume the necessarycounterions act as neither acids nor bases. species relative pH of0.1M aqueous solution HF ▼(Choose one) ClO2− ▼(Choose one) HClO2 1(lowest) H2O 4 NO2− 7 OH− ▼(Choose one) F− 6 HNO2 ▼(Choose one)
