Problem

For three clear, colorless solutions at 25 °C the reported hydronium ion concentrations are: 1. 1.0×10−4 M1.0\times10^{-4}\,\text{M} 2. 5.0×10−9 M5.0\times10^{-9}\,\text{M} 3. 2.5×10−2 M2.5\times10^{-2}\,\text{M} Arrange the solutions in order of decreasing basicity (most basic to least basic).
