When a substance is ionic, it means it comprises positively charged ions (cations) and negatively charged ions (anions), which are held together by electrostatic forces. In solid state, these substances form a lattice structure, providing high melting and boiling points. Ionic compounds conduct electricity when melted or dissolved in water due to the free movement of ions, allowing them to carry the electric current.
FAQs & Answers
- What defines a substance as ionic? A substance is ionic when it consists of positively charged ions (cations) and negatively charged ions (anions) held together by electrostatic forces.
- Why do ionic compounds have high melting and boiling points? Ionic compounds have high melting and boiling points due to the strong electrostatic forces holding the ions together in a lattice structure.
- Can ionic substances conduct electricity? Yes, ionic substances conduct electricity when melted or dissolved in water because the ions are free to move and carry electric current.
