Electrolytes

Front

What is an electrolyte?

Back

An electrolyte is a substance that dissociates into ions when dissolved in water, allowing the solution to conduct electricity.

What is the dissociation equation for ZnCl₂?

Back

ZnCl_2(s) --> Zn²⁺_(aq) + 2Cl^-_(aq)

Front

What is the difference between strong and weak electrolytes?

Back

Strong electrolytes completely dissociate into ions in solution, while weak electrolytes only partially dissociate.

Front

Which of the following is not an electrolyte: KBr, LiOH, RbNO₃, CH₄?

Back

CH₄ is not an electrolyte.

Front

What happens to NaCl when it is dissolved in water?

Back

NaCl dissociates into Na⁺ and Cl^- ions, which are surrounded by water molecules.

Front

What is a weak electrolyte?

Back

A weak electrolyte is a substance that only partially ionizes in solution, such as acetic acid (CH₃COOH).

Front

What is the role of water in the dissociation of ionic compounds?

Back

Water molecules stabilize the ions formed during dissociation through ion-dipole interactions.

Front

What is the dissociation equation for BaF₂?

Back

BaF_2(s) --> Ba²⁺_(aq) + 2F^-_(aq)

Front

What type of ions are produced when KBr dissolves in water?

Back

KBr produces K⁺ and Br^- ions in solution.

Front

What is the significance of ion-molecule attractions in solutions?

Back

Ion-molecule attractions are crucial for the solubility of ionic compounds in water and the conductivity of the solution.
