H2SO4 + Al(OH)3 = Al2(SO4)3 + H2O

  • Step 2 : Record the moles of each element on the reactant and product sides.
Element Reactant Product

No. of moles in reactant and product
  • Step 3 : Now, the number of moles present on each side of the reactant and product must be equal in order to balance the chemical equation. In this case, the number of moles in each element varies.
  • Step 4 : A chemical equation must be balanced by performing the following actions.
  • Al(OH)3 needs to have the reactant side multiplied by 2.
  • On the reactant side, H2SO4 needs to be multiplied by 3.
  • On the product side, H2O needs to be multiplied by 6.
  • Step 5 : Finally, the balanced chemical equation is

3H2SO4 + 2Al(OH)3 = Al2(SO4)3 + 6H2O

H2SO4 + Al(OH)3 net ionic equation

2Al(OH)3 + 6H+ = 2Al3+ + 6H2O

H2SO4 + Al(OH)3 conjugate pairs

The conjugate acid-base pairs are:

  • H2SO4 (Conjugate base) = HSO4
  • H2O (Conjugate base) = OH

Is H2SO4 + Al(OH)3 a buffer solution

H2SO4 + Al(OH)3 is not a buffer solution due to the presence of the strong acid H2SO4.

Is H2SO4 + Al(OH)3 a complete reaction

The reaction between H2SO4 and Al(OH)3 is complete. Since all of the reactant’s moles are completely converted and consumed by the product at equilibrium.

Is H2SO4 + Al(OH)3 an exothermic or endothermic reaction

H2SO4 + Al(OH)3 is an endothermic reaction because heat is produced on the product side.

Is H2SO4 + Al(OH)3 a redox reaction

H2SO4 + Al(OH)3 is not a redox reaction because the oxidation state of the central metal atom in the reactant as well as the product side does not change.

Is H2SO4 + Al(OH)3 a precipitation reaction

H2SO4 + Al(OH)3 reaction involves the formation of a salt hence it is a precipitation reaction.

Is H2SO4 + Al(OH)3 reversible or irreversible reaction

H2SO4 + Al(OH)3 is an irreversible reaction because the products once formed cannot be converted into reactants.

Is H2SO4 + Al(OH)3 displacement reaction

H2SO4 + Al(OH)3 is a displacement reaction because the Al transforms into Al2(SO4)3 on the product side, and the hydrogen in the H2SO4 in the reactant is displaced.


A mineral acid made up of the elements hydrogen, oxygen, and sulfur is called sulphuric acid. An amorphous, white powder is what aluminum hydroxide takes on.
