Magnesium acts as an oxidant when added to the aluminum ions, and consquently it will oxidize the aluminum and take it out of the solution forming aluminum solid and then the mangesium itself will go into the solution since it will be oxidezed by the aluminum.
The equation would be:
Mg (s) + Al³⁺ (aq) → Mg²⁺ (aq) + Al (s)
No metal is produced. The magnesium reacts with the water and forms hydrogen gas and magnesium hydroxide.
it decreases
Aluminium forms aluminate salt with a strong base (Alkali) in aqueous medium. 2Al + 2NaOH + 2H2O ----> 2NaAlO2 + 3H2
It will leave a solid salt, consisting of the ions.
it would explod
the solution becomes pink
No reaction occurs
it decreases
Aluminium forms aluminate salt with a strong base (Alkali) in aqueous medium. 2Al + 2NaOH + 2H2O ----> 2NaAlO2 + 3H2
Mg+AlCl=MgCl+Al Magnesium+Aluminium chloride=Magnesium chloride+ Aluminium This happens because magnesium is a more reactive element then aluminum so chlorine swaps places and forms a new compound with magnesium.
In aqueous solution, H2 is evolved at the cathode (instead of sodium) and chlorine gas is collected at the anode.
Double Replacement
Magnesium does not seem to react with dilute aqueous alkalis or bases. However, it does react with acids like sulfuric acid by dissolving in it.
It will leave a solid salt, consisting of the ions.
hello tarryn
it would explod
the solution becomes pink
If the solution is not basic then the pH will fall below 7
