Understanding Cations and Anions
What Are Cations?
Cations are positively charged ions formed when atoms or molecules lose one or more electrons. These ions are attracted to the cathode during electrochemical processes. In aqueous solutions, cations often influence the solubility of compounds, conduct electricity, and participate in various chemical reactions.
Common Characteristics of Cations:
- Carry a positive charge due to loss of electrons
- Typically metal ions or positively charged polyatomic ions
- Play crucial roles in ionic bonding and electrochemistry
What Are Anions?
Anions are negatively charged ions created when atoms or molecules gain electrons. They migrate toward the anode in electrochemical settings and are integral to many processes, including forming salts and participating in biological systems.
Common Characteristics of Anions:
- Carry a negative charge due to gain of electrons
- Usually nonmetals or polyatomic ions
- Involved in acid-base reactions, electrolysis, and ionic compounds
