WebFeb 26, 2024 · As RbOH dissociates into Rb 1+ and OH 1-, the OH 1- concentration is also 1.9 x 10 -3. [H 1+] [OH 1-] = 10 -14, so the [H 1+] = 10 -14 / 1.9 x 10 -3 = 5.3 x 10 -12 . Take the negative log of this to get pH = 11.3. The log of 1.9 x 10 -3 is -2.72, but pOH is the negative of this which is 2.72. pH + pOH = 14, so you can calculate pH from this also.
