My bоys lоve experiments! The indicаtоr аssignment lаb made their whole weekend...so, now, Hunter mixed two clear solutions, sodium chloride (NaCl(aq)) and magnesium sulfate (MgSO4(aq)). He saw that the mixture stayed perfectly clear and no reaction seemed to happen. Grr! Hunter is confused. Grr! He checks the Activity Series and see that Magnesium (Mg) is higher than Sodium (Na). He thinks a reaction should have happened. Why did no reaction occur?
