Chemical Reactions I: Net ionic equations
4.5 Net ionic equations – No driving force for reaction = no reaction
Subjects: Chemical reactions, net ionic equations
Description: Two chemicals are mixed together resulting in no reaction.
- 0.1 M Sodium hydroxide, NaOH‡
- 0.1 M Potassium acetate (KCH3CO2)‡
- 2 100 mL beakers
- 1 250 mL beaker
‡ Sodium hydroxide is located in the cabinet under the hood. 0.1 M Potassium acetate is located in the solutions cabinet.
- Pour the individual solutions into labeled 100 mL beakers.
- Pour both beakers into the 250 mL beaker.
- Observe that no reaction takes place.
NaOH(aq) + KCH3CO2(aq) → Na(CH3CO2)(aq) + KOH(aq)
Na+(aq)+ OH-(aq)+ K+(aq)+ CH3CO2-(aq)→
Na+ + CH3CO2-(aq) + K+(aq) + OH-(aq)
All ions are soluble and are spectator ions. Therefore no reaction takes place.
Check that the solution is between pH 2 and 12. It can be flushed down the drain with water.
