If you"re asking what ns think you"re asking, then you"re dealing with a neutralization reaction.

A neutralization reaction is said to take ar when a base reacts v an acid to kind salt and water.

In your case, sulfuric acid, #"H"_2"SO"_4#, a strong acid, will certainly react through magnesium hydroxide, #"Mg"("OH")_2#, a weak base, to kind aqueous magnesium sulfate, #"MgSO"_4#, and water.

#"Mg"("OH")_ (2(s)) + "H"_ 2"SO"_ (4(aq)) -> "MgSO"_ (4(aq)) + 2"H"_ 2"O"_((l))#

Now, friend can acquire a sense of why this is a neutralization reaction by looking at the net ionic equation.

Magnesium hydroxide is a weak base, which way that it does no dissociate totally in aqueous systems to kind magnesium cations, #"Mg"^(2+)#, and hydroxide anions, #"OH"^(-)#.

Instead, an equilibrium will certainly be established in between the undissolved solid and the dissolved ions

#"Mg"("OH")_ (2(s)) rightleftharpoons "Mg"_ ((aq))^(2+) + 2"OH"_((aq))^(-)#

Sulfuric acid, ~ above the other hand, is a solid acid, for this reason it will ionize completely in aqueous equipment to relax hydrogen ions, #"H"^(+)# ,and sulfate anions, #"SO"_4^(2-)#

#"H"_ 2"SO"_ (4(aq)) -> 2"H"_ ((aq))^(+) + "SO"_(4(aq))^(2-)#

These hydrogen ions will react with the hydroxide anions and essentially neutralize each other, therefore why this is a neutralization reaction.

In turn, this will drive magnesium hydroxide"s dissociation equilibrium additional to the right, which in turn will produce more hydroxide anions and also dissolve the solid.

The magnesium cations and also the sulfate anions are spectator ions since they exist as ion on both political parties of the equation.

You will certainly have

#color(red)(cancel(color(black)("Mg"_ ((aq))^(2+)))) + 2"OH"_ ((aq))^(-) + 2"H"_ ((aq))^(+) + color(red)(cancel(color(black)("SO"_ (4(aq))^(2-)))) -> color(red)(cancel(color(black)("Mg"_ ((aq))^(2+)))) + color(red)(cancel(color(black)("SO"_ (4(aq))^(2-)))) + 2"H"_ 2"O"_((l))#

The net ionic equation will therefore be

#color(green)(|bar(ul(color(white)(a/a)color(black)(2"OH"_ ((aq))^(-) + 2"H"_ ((aq))^(+) -> 2"H"_ 2"O"_((l)))color(white)(a/a)|)))#

Now, it"s worth noting that a neutralization reaction is actually a specific case of a double instead of reaction.

As girlfriend know, double instead of reactions involve the exchange of ions between two compounds. In this case, the magnesium cations trade places with the hydrogen cations.
