Answer and explanation
Na⁺ and NO₃⁻ remain dissolved unchanged.
Response criteria
- State a scientifically accurate conclusion.
- Show the calculation or mechanism that supports it.
- Include units, conditions, or limits where relevant.
Problem 2
Why leave a solid intact in a net ionic equation?
Answer and explanation
It is not represented as independently mobile aqueous ions.
Response criteria
- State a scientifically accurate conclusion.
- Show the calculation or mechanism that supports it.
