Webb1 sep. 2016 · The hydroxyl values determined by the titration method were 300 and 228 mg KOH/g, respectively, which is in good agreement with the theoretical values. The results indicated that the side reactions, such as the formation of disulfide, were minimized, and the complete/quantitative transformation of carbon–carbon double bonds to hydroxyl … WebbThe product of the molarity of hydronium and hydroxide ion is always 1.0 × 10 − 14 (at room temperature). (2) K w = [ H 3 O +] [ O H −] = 1.0 × 10 − 14 Equation 2 also applies to all aqueous solutions. However, K w does change at different temperatures, which affects the pH range discussed below.
