WebThe equation representing the ionization of any weak acid, B, and the equilibrium expression, K b, are shown below. Note: This expression, K b, is based on the general form for K c. The designation K b is used to indicate that it is the equilibrium constant for the reaction of a base with water. Top. Calculating K b. To calculate the ionization ... WebThe strength of a weak acid depends on how much it dissociates: the more it dissociates, the stronger the acid. In order to quantify the relative strengths of weak acids, we can look at the acid dissociation constant K_\text {a} K a, the equilibrium constant for the acid dissociation reaction. WebStep 1: Set up the Kb equation for a weak base. Step 2: The molar concentration of your base will represent HB in the Kb equation. The undissociated amount. Step 3: In weak bases, if the... how is keto even healthy
