O pOH é uma escala utilizada para expressar a concentração, em mol/L, dos íons hidróxidos presentes na solução. O pOH pode ser calculado por meio da fórmula −log [OH −]. O que é pOH? O pOH está relacionado à concentração dos íons hidróxido, OH⁻. Sua fórmula é: pOH = −log [OH⁻] O cálculo segue a mesma lógica utilizada para o pH.
This article provides an in-depth understanding of the pOH formula, its concept, relation with pH, and how to calculate it. It also includes frequently asked questions on the topic. pOH is a measure of hydroxide ion concentration in a solution, indicating its basicity. It complements the pH scale, with the relationship pH + pOH = 14. Calculating pOH involves the formula pOH = -log[OH⁻].
pOH Graphs Using the formula (equation) pOH = -log 10 [OH -] we can calculate the pOH of solutions with varying OH - concentrations and plot these values on a graph. An example is shown below: Summary pOH is the negative logarithm of the hydroxide-ion concentration. Review What is the formula for calculating pOH? What pOH value is indicative of an acidic solution? A pOH value of 3 would indicate what type of solution?
