Final answer:
No reaction occurs between sodium sulfate and sodium bromide in solution; both simply dissociate into their constituent ions with no net ionic equation beyond the individual dissociations.
Step-by-step explanation:
The student seems to be confused about the reaction between sodium sulfate (Na2SO4) and sodium bromide (NaBr). In an aqueous solution, both sodium sulfate and sodium bromide will dissociate into their respective ions, but no reaction will occur because no precipitate or gas is formed, and no weak electrolyte is produced.
The molecular equation for the dissociation of Na2SO4 is as follows:
- Na2SO4(s) → 2Na+(aq) + SO42-(aq)
And the molecular equation for the dissociation of NaBr would be:
- NaBr(s) → Na+(aq) + Br-(aq)
However, since Na2SO4 and NaBr both produce Na+ ions in solution, and Na+ is not reacting with any other ion to form a new compound, there isn't a conventional reaction taking place. Therefore, no ionic or net ionic equation is needed beyond the dissociation equations provided for each compound.
