WebFeb 3, 2024 · K a is the equilibrium constant for the dissociation reaction of a weak acid.A weak acid is one that only partially dissociates in water or an aqueous solution. The value of K a is used to calculate the pH of weak acids.The pK a value is used to choose a buffer when needed. Choosing an acid or base where pK a is close to the pH needed gives the … WebScience Chemistry Consider the sparingly soluble salt AB (s) for which AB (s) ⇌ A+ (aq) + B− (aq). Calculate the Ksp value of the salt if the concentration of the A+ ion in a saturated solution of AB is 937.5 × 10–5 M. Provide your answer to eight decimal places and without units.

The rate constant, k, gives a direct measure of the relative reaction rate. A very small value for the rate constant equates to a very slow reaction in general. Equally, a large value for the rate constant means a large value for the rate and that the reaction is rapid.
