2023年7月20日 · The strengths of Brønsted-Lowry acids and bases in aqueous solutions can be determined by their acid or base ionization constants. Stronger acids form weaker conjugate bases, and weaker acids …

2023年1月30日 · Acids and bases behave differently in solution based on their strength. Acid or base "strength" is a measure of how readily the molecule ionizes in water. Some acids and bases ionize rapidly and almost completely in solution; these are called strong acids and strong bases. For example, hydrochloric acid (HCl) is a strong acid.

The strength of acids and bases, i.e., the extent of dissociation of the dissolved acid or base into ions in water is described. The relative strength of the acid/conjugate base pair is also …

The relative strength of an acid or base is the extent to which it ionizes when dissolved in water. 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 ...

Some of the common strong acids and bases are listed here. The relative strengths of acids may be determined by measuring their equilibrium constants in aqueous solutions. In solutions of the same concentration, stronger acids ionize to a greater extent, and so yield higher concentrations of hydronium ions than do weaker acids.

Just as for acids, the relative strength of a base is reflected in the magnitude of its base-ionization constant (Kb) in aqueous solutions. In solutions of the same concentration, stronger bases ionize to a greater extent, and so yield higher hydroxide ion concentrations than do weaker bases.

We can rank the strengths of acids by the extent to which they ionize in aqueous solution. The reaction of an acid with water is given by the general expression: HA(aq) + H 2O(l) ⇌ H 3O + (aq) + A − (aq) Water is the base that reacts with the acid HA, A − is the conjugate base of the acid HA, and the hydronium ion is the conjugate acid of water.

Different acids differ in their ability to donate H +. Stronger acids, such as HCl, react almost completely with water, whereas weaker acids, such as acetic acid (CH 3 CO 2 H), react only slightly. The exact strength of a given acid HA in water solution is described using the acidity constant (Ka) for the acid-dissociation equilibrium.
