SUMMARY
The discussion focuses on calculating the hydrogen ion concentration ([H+]) and pH of a 100 mM potassium hydroxide (KOH) solution. KOH fully dissociates into K+ and OH- ions, leading to a pOH calculation using the formula pOH = -log[OH-]. The correct concentration of hydroxide ions in a 100 mM KOH solution is 0.1 M, resulting in a pOH of 1. The pH can then be determined using the relationship pH + pOH = 14, yielding a pH of 13.
