Question

question 5 of 10
what does a complete ionic equation look like?

a. all ionic substances are written as separate ions in solution.

b. all substances are labeled with the oxidation states of the atoms.

c. all ionic substances are written with the state symbol (aq) after it.

d. all substances are written as ionic compounds bonded together.

Explanation:

To determine the correct option, we analyze each choice:

• Option A: A complete ionic equation separates all ionic substances (that are in aqueous solution and dissociate) into their respective ions. This matches the definition of a complete ionic equation.
• Option B: Labeling with oxidation states is related to redox reactions and not the definition of a complete ionic equation.
• Option C: Just adding the (aq) state symbol doesn't define a complete ionic equation; it's about separating ions, not just labeling the state.
• Option D: A complete ionic equation does not write ionic compounds as bonded together; it separates them into ions.

Answer:

A. All ionic substances are written as separate ions in solution.
