Double Displacement and Net Ionic Equations

Front

What is a Net Ionic Equation?

Back

A chemical equation showing only the species which are actively involved in the reaction.

Front

What is a double displacement reaction?

Back

A reaction where two compounds exchange ions to form two new compounds.

Front

What is the general form of a double displacement reaction?

Back

AB + CD → AD + CB, where A and C are cations and B and D are anions.

Front

What is the role of a spectator ion in a chemical reaction?

Back

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

Front

How do you identify a precipitate in a chemical reaction?

Back

A precipitate is identified as a solid that forms and separates from a liquid mixture.

Front

What is the significance of balancing chemical equations?

Back

Balancing chemical equations ensures the law of conservation of mass is followed, meaning the number of atoms of each element is the same on both sides.
