Names and Formulas of Acid Anions

6 Given the name (or formula) of an ion formed by the step-by-step ionization of a polyprotic acid fi om a Group 4A/14,5A/15, or 6A/16 element, write its formula (or name). [Pg.156]

Polyprotic acids do not lose their hydrogens all at once, but rather one at a time. The intermediate anions produced are stable chemical species that are the negative ions in many ionic compounds. The hydrogen-bearing acid anion, as it is called, releases a hydrogen ion when dissolved in water, just like any other acid. [Pg.156]

Baking soda, commonly found in kitchen cabinets, contains the acid anion HCO3 . It can be regarded as the intermediate step in the ionization of carbonic acid [Pg.156]
