WebApr 17, 2024 · pH ≈ 11.5 Explanation: When put in water, the KOH dissolves into K+ and OH − ions, with the latter increasing the pH of the solution. As hydroxides can be considered … WebFigure 14.4 (a) A research-grade pH meter used in a laboratory can have a resolution of 0.001 pH units, an accuracy of ± 0.002 pH units, and may cost in excess of $1000. (b) A portable pH meter has lower resolution (0.01 pH units), lower accuracy (± 0.2 pH units), and a far lower price tag. (credit b: modification of work by Jacopo Werther)
