Weak and strong should not be mistaken for dilute and concentrated. A dilute acid has the acid molecules mixed with a large amount of water, so that there is only a low concentration of H + ions.
Sep 16, 2022 · Contributions & Attributions. 14.7: Strong and Weak Acids and Bases is shared under a CK-12 license and was authored, remixed, and/or curated by Marisa Alviar-Agnew & Henry Agnew. Acids are classified as either strong or weak, based on their ionization in water. A strong acid is an acid which is completely ionized in an aqueous solution.
Apr 20, 2023 · A base that is a strong electrolyte is called a strong base, while a base that is a weak electrolyte is called a weak base. Classifying acids or bases as strong or weak has nothing to do with their concentration. It is possible to have a dilute solution of a strong acid or base and it is also possible to have a concentrated solution of a weak ...
If the ionization reaction is essentially complete, the acid or base is termed strong; if relatively little ionization occurs, the acid or base is weak. As will be evident throughout the remainder of this chapter, there are many more weak acids and bases than strong ones. The most common strong acids and bases are listed in Figure 14.6.
Water is the acid that reacts with the base, HB + is the conjugate acid of the base B, and the hydroxide ion is the conjugate base of water. A strong base yields 100% (or very nearly so) of OH − and HB + when it reacts with water; Figure 1 lists several strong bases. A weak base yields a small proportion of hydroxide ions.
May 16, 2023 · In contrast, acetic acid is a weak acid, and water is a weak base. Consequently, aqueous solutions of acetic acid contain mostly acetic acid molecules in equilibrium with a small concentration of \ (H_3O^+\) and acetate ions, and the ionization equilibrium lies far to the left, as represented by these arrows:

The ions react very easily to reform the acid and the water. At any one time, only about 1% of the ethanoic acid molecules have converted into ions. The rest remain as simple ethanoic acid molecules. Most organic acids are weak. Hydrogen fluoride (dissolving in water to produce hydrofluoric acid) is a weak inorganic acid that you may come ...
