WitrynapKa = – log 10 [Ka] We can determine whether an acid is a strong acid or a weak acid by looking at its pKa value. The acid is weak if the pKa value is high. Because a greater pKa number suggests that Ka is low, this is the case. The value of [A –][H +] should be lower than the value of [HA] in order for Ka to be low. This indicates that the ... Witryna14 sie 2024 · The larger the Ka, the stronger the acid and the higher the H + concentration at equilibrium. Like all equilibrium constants, acid–base ionization …

WitrynaOH– = Hydroxide ion. Hydroxide (OH–) is also known as the hydroxyl ion. When water dissociates or comes apart into its component parts it forms OH – (hydroxide ions) and H 3 O + (hydronium ions). 2H2O ⇆ OH– and H3O+. This reaction is reversible. The hydroxide ion also reacts with the hydronium ion (H3O+) to become two water … service urbanisme poisy https://tommyvadell.com
