This is a two part question. Calculate either [H3O+] or[OH−] for each of the solutions at 25 °C.
Solution A: [OH−]= 2.91×10−7 M Solution A: [H3O+]=M
Solution B: [H3O+]=9.81×10−9 M   Solution B:[OH−]= M
Solution C: [H3O+]=0.000669 M Solution C: [OH−]=M
Which of these solutions are basic at 25 °C? (You areable to pick more than one option). Solution C, Solution A, andSolution B are the three options.
Solution C: [H3O+]= 0.000669 M
Solution A: [OH−]= 2.91×10−7 M
Solution B: [H3O+]= 9.81×10−9 M
