Ian uses litmus paper to determine whether five unknown solutions are acids or bases. The litmus paper turns red when the pH is
4.5 or below and blue when the pH is 8.2 or above. Ian records the results in the data table.
Ian accidentally spills a beaker of an unknown solution. It splashes onto the strip he used to test Solution 1, and the strip turns from red to blue. Based on this observation, which conclusion could Ian make about the solution that he spilled?
