Koh with water
WebMany industrial processes use a hydrofluoric acid (HF) catalyst in their manufacturing process. Part of this acid must be neutralized with a base chemical, often potassium hydroxide (KOH). Typically, the resulting material, potassium fluoride (KF), must be classified, handled and disposed as waste. WebMar 6, 2024 · When calculating pH of KOH solutions, following theories and equations are important. Theory 1: KOH dissociates completely in the water to K + and OH-ions. Theory 2: Due to complete dissociation, initial concentration of KOH is equal to OH-concentration. Equation 1: Relationship of pH + pOH = 14; Equation 2: pH = -log 10 [H 3 O + (aq)] Equation …
