WebApr 10, 2024 · A pH of 12.4 indicates a pOH of 14-12.4 = 1.6. As pOH = -log [OH - ], the [OH -] is the antilog of - 1.6 = 0.0251 M/L. The number of grams of OH - required would be 0.0251 moles / L x 17.0 g/mole x 1L/1000 mL x 500 mL = 0.213 g OH -. The mass of KOH needed then is molar mass KOH / molar mass OH - x g OH -.

WebDec 30, 2024 · A titration curve is a plot of the concentration of the analyte at a given point in the experiment (usually pH in an acid-base titration) vs. the volume of the titrant added.This curve tells us whether we are dealing with a weak or strong acid/base for an acid-base titration. The curve around the equivalence point will be relatively steep and smooth when … WebAs the first step, we are going to calculate pOH value and then calculate the pH using the relationship of pH and pOH. Calculate pOH pOH = -log (OH -(aq)) pOH = -log ( 0.1) pOH = 1 Apply the relation of pH and pOH pH + pOH = 14 (at 25 0 C) pH + 1 = 14 pH = 13 Let's solve example 1 according to method 2. We know the concentration of OH - ions WebSep 11, 2024 · Respiratory burst oxidase homologs (Rbohs) play a predominant role in reactive oxygen species (ROS) production, which is crucial in plant growth, differentiation, as well as their responses to biotic and abiotic stresses.
