Read each question carefully and provide clear, concise answers. For net ionic equations, ensure correct states of matter and balanced charges.
Understanding ionic bonds is crucial for net ionic equations. An ionic bond is formed between a metal and a nonmetal, where electrons are transferred, creating charged ions.
1. Which of the following statements best describes a spectator ion?
An ion that participates in the reaction and forms a precipitate.
An ion that is present in the solution but does not participate in the chemical reaction.
An ion that changes its oxidation state during the reaction.
An ion that is always a cation.
2. When writing a total ionic equation, which of the following compounds should be dissociated into ions?
Insoluble solids
Strong acids and strong bases
Covalent compounds
Water
3. A precipitate is an solid formed in a solution during a chemical reaction.
4. To write a net ionic equation, you must first write the ionic equation and then cancel out the ions.
5. Write the balanced molecular equation, complete ionic equation, and net ionic equation for the reaction between aqueous silver nitrate and aqueous sodium chloride. Clearly identify any spectator ions and the precipitate formed.
