15 Facts on H2SO4 + Ba: What, How To Balance & FAQs

Chemical reactions involves collision of two or more reacting species in proper orientation to form important products. Let us talk about the chemical reactivity of H2SO4 and Ba.

Sulphuric acid is a strong acid with defining industrial applications. Due to its high miscibility in water, it is strongly corrosive towards many metals and non-metals. Barium is a very reactive alkaline earth metal. The metal is utilised in high temperature semiconductors and fire crackers industries.

The reactivity of H2SO4 and Ba has significance in the petroleum industry, used in paints and varnishes. Furthermore, the chemical reactions can be explored on following criteria discussed below.

What is the product of H2SO4 and Ba?

Barium sulfate and hydrogen gas is formed when H2SO4 + Ba reacts.

H2SO4 + Ba = BaSO4 + H2

What type of reaction is H2SO4 + Ba?

H2SO4 + Ba is a substitution reaction where hydrogen in sulphuric acid is substituted by barium to form barium sulfate.

How to balance H2SO4 + Ba?

The following reaction is balanced according to the mentioned algebraic method :

Ba + H2SO4 = BaSO4 + H2

  • Unknown coefficients are represented by variables (A, B, C, and D) that are assigned to each reactant and product in the equation.
  • A Ba + B H2SO4 = C BaSO4 + D H2
  • Now, the equation is solved by an appropriate number, considered to be the coefficient of reactants and products.
  • Ba = A = C, H = 2B = 2D, S = B = C, O = 4B = 4C
  • Using the Gauss elimination method, all the variables and coefficients are calculated, and the result is
  • A = 1, B = 1, C = 1, and D = 1
  • So, the overall balanced equation is,
  • Ba + H2SO4 = BaSO4 + H2

H2SO4 + Ba titration

The titration system of Ba + H2SO4 is not possible because Ba is a metal which cannot be used in titration.

H2SO4 + Ba net ionic equation

The net ionic equation of Ba + H2SO4 is

Ba (s) + 2H+ (aq) + SO4-2 (aq) = BaSO4 (s) + H2 (g)

The net ionic equation is created using the procedures described below:

  • Write the balanced chemical equation first, then illustrate the physical conditions of the reactants and products
  • Ba (s) + H2SO4 (aq) = BaSO4 (s) + H2 (g)
  • Now, pure solid substances and molecules do not dissociate, whereas strong acids, bases, and salts dissociate into ions
  • Thus, the net ionic equation is
  • Ba (s) + 2H+ (aq) + SO4-2 (aq) = BaSO4 (s) + H2 (g)

H2SO4 + Ba conjugate pairs

  • H2SO4 forms a conjugate base as HSO4
  • Ba cannot form conjugate pairs because it contains no proton.

H2SO4 and Ba intermolecular forces

  • H2SO4 molecules are bonded together via dipole-dipole interactions, van der Waals dispersion forces, and strong hydrogen bonds.
  • Ba metal ions interacts using intermolecular forces.

H2SO4 + Ba reaction enthalpy

H2SO4 + Ba reports reaction enthalpy of -239.02 kJ/mol.

Is H2SO4 + Ba a buffer solution?

H2SO4 + Ba cannot work as buffer solution because neither strong acid (H2SO4) nor metal (Ba) can form a buffer.

Is H2SO4 + Ba a complete reaction?

H2SO4 + Ba is a complete reaction as barium sulfate and hydrogen gas are formed as stable products.

Is H2SO4 + Ba an exothermic or endothermic reaction?

H2SO4 + Ba is an exothermic reaction because heat is liberated on addition of sulphuric acid.

Is H2SO4 + Ba a redox reaction?

H2SO4 + Ba is not a redox reaction because only Ba undergoes oxidation reaction.

Is H2SO4 + Ba a precipitation reaction?

H2SO4 + Ba is a precipitation reaction because insoluble barium sulfate precipitates down at the end of reaction.

Is H2SO4 + Ba reversible or irreversible reaction?

H2SO4 + Ba is an irreversible reaction because the products formed BaSO4 cannot be changed back to the reactants.

Is H2SO4 + Ba displacement reaction?

H2SO4 + Ba is a displacement reaction because single displacement of sulphate group from hydrogen to barium is noticed.

Conclusions

The reaction of sulphuric acid with barium has several industrial and commercial implications. Barium passively reacts with sulphuric acid and thereby stops the reaction by forming the insoluble coating of barium sulfate on the surface. Barium sulfate owing to its low toxicity is used in X-ray imaging.
