Chapter 17 : Additional Aspects of Aqueous Equilibria

Section 2: Buffered Solutions. Chapter 17 : Additional Aspects of Aqueous Equilibria. Introduction. Solutions prepared with common ions have a tendency to resist drastic pH changes even when subjected to the addition of strong acids or bases. Such solutions are called buffered solutions .

Review: Ions

Review: Ions. Cation: Formed when atoms lose electrons metals form cations Common cations: Grp 1 = +1 Grp 2 = +2 Grp 13 = +3 Anion Formed when atoms gain electrons Non-metals form anions Common anions: Grp 15 = -3 Grp 16 = -2 Grp 17 = -1. Common ions and the periodic table.

Ions

Ions. IONS. IONS are atoms or groups of atoms with a positive or negative charge. Taking away an electron from an atom gives a CATION with a positive charge Adding an electron to an atom gives an ANION with a negative charge .
