Which equation type shows every dissolved ionic reactant and product as its separate ions?
AThe net ionic equation
BThe complete ionic equation
CThe molecular equation
DThe half-reaction equation
Answer & Solution
Correct answer: B. The complete ionic equation
1. Ionic compounds that dissolve in water break apart into their ions.
2. Writing every one of those ions out gives the complete ionic equation.
3. Species that stay undissolved, such as solid AgCl, are still written as whole formulas.
4. The net ionic equation goes one step further and drops the spectator ions.
5. A half-reaction shows only the loss or gain of electrons by one species, not the whole change.
