# Four separate beakers each contain a \(0.10\text{ M}\) aqueous solution at \(25\ ^\circ\text{C}\):

Solution 1: \(\text{HCl(aq)}\)
Solution 2: \(\text{HC}_2\text{H}_3\text{O}_2\text{(aq)}\)
Solution 3: \(\text{NH}_3\text{(aq)}\)
Solution 4: \(\text{Ba(OH)}_2\text{(aq)}\)

Which of the following correctly ranks the four solutions in order of increasing \(\text{pH}\) and identifies the solution with the greatest electrical conductivity?

Four separate beakers each contain a \(0.10\text{ M}\) aqueous solution at \(25\ ^\circ\text{C}\):

Solution 1: \(\text{HCl(aq)}\)
Solution 2: \(\text{HC}_2\text{H}_3\text{O}_2\text{(aq)}\)
Solution 3: \(\text{NH}_3\text{(aq)}\)
Solution 4: \(\text{Ba(OH)}_2\text{(aq)}\)

Which of the following correctly ranks the four solutions in order of increasing \(\text{pH}\) and identifies the solution with the greatest electrical conductivity?

- **A.** \(\text{pH}\) order: Solution \(2 <\) Solution \(1 <\) Solution \(3 <\) Solution \(4\); Greatest conductivity: Solution \(1\)
- **B.** \(\text{pH}\) order: Solution \(2 <\) Solution \(1 <\) Solution \(4 <\) Solution \(3\); Greatest conductivity: Solution \(4\)
- **C.** \(\text{pH}\) order: Solution \(1 <\) Solution \(2 <\) Solution \(4 <\) Solution \(3\); Greatest conductivity: Solution \(1\)
- **D.** \(\text{pH}\) order: Solution \(1 <\) Solution \(2 <\) Solution \(3 <\) Solution \(4\); Greatest conductivity: Solution \(4\)
