Strong acids ionization

There are two types of acids, strong and weak, which differ in the extent of their ionization in water. Strong acids ionize completely, forming H+ ions and anions. A typical strong acid is HC1. It undergoes the following reaction on addition to water ... 

As pointed out in Chapter 13, strong acids ionize completely in water to form H30+ ions strong bases dissolve in water to form OH- ions. The neutralization reaction that takes place when any strong acid reacts with any strong base can be represented by a net ionic equation of the Bronsted- Lowry type ... 

Sulfonic acids, RS03H, particularly in the form of their salts RS03 M+, are far and away the most frequently encountered of the organic oxyacids of sulfur. They are strong acids, ionizing completely in water to RSO and H30+. 

A substance that produces H+(aq) ions in aqueous solution. Strong acids ionize completely or almost completely in dilute aqueous solution. Weak acids ionize only slightly. 

As a matter of convenience we place acids into two classes strong acids and weak acids. Strong acids ionize (separate into hydrogen ions and stable anions) completely, or very nearly completely, in dilute aqueous solution. The seven common strong acids and their anions are listed in Table 4-5. Please learn this short list you can then assume that other acids you encounter are weak. 

Because strong acids ionize completely or very nearly completely in dilute solutions, their solutions contain predominantly ions rather than acid molecules. Consider the ionization of hydrochloric acid. Pure hydrogen chloride, HCl, is a molecular compound that is a gas at room temperature and atmospheric pressure. When it dissolves in water, it reacts nearly 100% to produce a solution that contains hydrogen ions and chloride ions ... 

A strong acid ionizes completely in solution it exists completely as ions in solution. A weak acid ionizes only slightly and exists as an equilibrium between the molecular acid and the ions it forms in solution. 

A strong acid ionizes almost 100% in aqueous solution. Eor example HCl ionization in water ... 

Write balanced equations showing how three of the common strong acids ionize to produce hydrogen ion. 

Because strong acids ionize completely, it s easy to calculate the concentration of the hydronium ion and chloride ion in solution if you know the initial concentration of the strong acid. For example, suppose that you bubble 0.1 moles (see Chapter 10 to get a firm grip on moles) of HCl gas into a liter of water. You can say that the initial concentration of HCl is 0.1 M (0.1 mol/L). 

The list of molecular compounds that are strong electrolytes is fairly short. It comprises the seven strong acids, which are listed in Table 4.1. A strong acid ionizes completely, resulting in a solution that contains hydrogen ions and the corresponding anions but essentially no acid molecules. 

Strong acids ionize completely in aqueous solution. (Only (he first ionization of the diprotic acid H2SO4 is complete.)... 

The strengths of acids are measured by their tendencies to transfer protons to water, which we regard as the reference solvent. A solution of a weak acid (HA) contains both undissociated acid and hydro-nium ions, and the concentration of ions is low. Strong acids ionize completely. 

Hydrated metal ions, particularly those with a charge of +3 or more, are Bronsted acids because they tend to lose H+ in aqueous solution. The acidity of a metal ion increases with charge and decreases with increasing radius. Hydrated iron(III) ion is a relatively strong acid, ionizing as follows ... 

There are many different acids, but as we learned in Chapter 4, relatively few qualify as strong. Strong Acid Ionization Reaction ...
