Total and Net Ionic Equations Flashcard

Front

What are spectator ions?

Back

Spectator ions are ions that do not participate in the chemical reaction and remain unchanged in the solution.

Front

What is a net ionic equation?

Back

A net ionic equation shows only the ions and molecules that are directly involved in the chemical reaction, omitting the spectator ions.

Front

What is an electrolyte?

Back

An electrolyte is a substance that produces ions in solution and conducts electricity.

Front

What are the three major cations that cause a substance to be insoluble, except for nitrates, acetates, and perchlorates?

Back

Lead (Pb²⁺), Silver (Ag⁺), and Mercury (Hg²⁺).

Front

What is the role of Na⁺ and Cl⁻ in the reaction CuCl₂(aq) + NaOH(aq) → Cu(OH)₂(s) + NaCl(aq)?

Back

Na⁺ and Cl⁻ are spectator ions in this reaction.

Front

Write the net ionic equation for the reaction of AgNO₃ and CaCl₂.

Back

Ag⁺(aq) + Cl⁻(aq) → AgCl(s).

Front

What does it mean for a substance to be soluble?

Back

A substance is soluble if it can dissolve in a solvent, typically water, to form a homogeneous solution.

Front

What is the difference between total ionic equation and net ionic equation?

Back

A total ionic equation shows all the ions present in the solution, while a net ionic equation only shows the ions that participate in the reaction.

Front

What is the significance of solubility rules in chemistry?

Back

Solubility rules help predict whether a compound will dissolve in water and guide the writing of net ionic equations.

Front

What is the formula for calculating the concentration of an electrolyte solution?

Back

Concentration (C) = moles of solute (n) / volume of solution (V) in liters.
