Define a weak acid or base. Calculation pH and pOH the a weak mountain or base equipment using straightforward formula, quadratic equation, and also including autoionization of water. Calculation the pH or pOH quickly.

You are watching: Which of the following is a weak acid

Weak acids and bases are just partially ionized in your solutions, whereas solid acids and also bases are totally ionized when liquified in water. Some usual weak acids and also bases are provided here. Furthermore, weak acids and also bases are very common, and also we conference them frequently both in the academic problems and also in everyday life. The ionization that weak acids and also bases is a princetoneclub.orgical equilibrium phenomenon. The equilibrium principles are important for the understanding of equilibria that weak acids and also weak bases. In this connection, you most likely realize that conjugate mountain of weak bases room weak acids and conjugate bases that weak acids space weak bases.

Ionization that Weak mountain

Acetic acid, \(\ceCH3COOH\), is a usual weak acid, and it is the ingredient the vinegar. That is partially ionized in that solution.

\<\ceCH3COOH \rightleftharpoons CH3COO- + H+\>

The framework of the acetate ion, \(\ceCH3COO-\), is displayed below.
