Acids and the Anions Derived from Their Total Ionization

5 Acids and the Anions Derived from Their Total Ionization 

5 Given the name (or formula) of an acid or ion in Table 6.5, write its formula (or name). 

The most familiar form of an acid is a molecular compound that reacts with water to produce a hydrated hydrogen ion and an anion. Examples of acids include HCl, HNO3, and HC2H3O2. Notice that the common characteristic among these formulas is that the ionizable hydrogen is written first in the formula. If HX represents an acid, its ionization equation can be written as 

An ion is said to be hydrated when it is surrounded by water molecules. In Section 6.10 you will learn about hydrated solid compounds that have water molecules as part of their structure. 

The hydronium ion, H3O+, is a simplified form of the hydrated hydrogen ion, a hydrogen ion that is bound to a number of water molecules, H+ (HjO). Removing a water molecule from both sides of the previous ionization equation leaves
