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)
When tin is placed into a magnesium sulfate solution, no reaction occurs since tin is lower in the reactivity series than magnesium. Tin does not displace magnesium from its salt solution.
As the concentration of H₃O⁺ increases in an aqueous solution, the pH decreases, shifting the equilibrium of the autoionization of water to the left. This results in a decrease in the concentration of hydroxide ions (OH⁻) in the solution.
When a piece of copper is placed in magnesium chloride solution, no reaction will occur because copper is less reactive than magnesium. Copper will remain unchanged in the solution.
When magnesium oxide is added to water, it will react to form magnesium hydroxide, a salt solution, and release heat. This reaction is exothermic and the magnesium hydroxide formed will be a white solid that will dissolve in water to form the salt solution.
Phenolphthalein in a solution containing magnesium hydroxide would remain colorless as it does not change color at a basic pH, where magnesium hydroxide is present. Phenolphthalein changes color in acidic solutions, not basic ones.
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.
When tin is placed into a magnesium sulfate solution, no reaction occurs since tin is lower in the reactivity series than magnesium. Tin does not displace magnesium from its salt solution.
hello tarryn
When magnesium chloride solution is mixed with sodium carbonate solution, a white precipitate of magnesium carbonate forms. This is a double displacement reaction where the magnesium ions from magnesium chloride exchange with the carbonate ions from sodium carbonate to form the insoluble magnesium carbonate.
As the concentration of H₃O⁺ increases in an aqueous solution, the pH decreases, shifting the equilibrium of the autoionization of water to the left. This results in a decrease in the concentration of hydroxide ions (OH⁻) in the solution.
When a piece of copper is placed in magnesium chloride solution, no reaction will occur because copper is less reactive than magnesium. Copper will remain unchanged in the solution.
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.
Magnesium acetate is obtained.
When magnesium oxide is added to water, it will react to form magnesium hydroxide, a salt solution, and release heat. This reaction is exothermic and the magnesium hydroxide formed will be a white solid that will dissolve in water to form the salt solution.
Will obtain magnisium nitrate{Mg(NO3)2} and H2 gas
i think that it would be displaced .... wont it?
