**Is H**_{2}SO_{4} + Ba a buffer solution?

_{2}SO

_{4}+ Ba a buffer solution?

**H _{2}SO_{4} + Ba cannot work as buffer solution because neither strong acid (H_{2}SO_{4}) nor metal (Ba) can form a buffer.**

_{2}SO

_{4}+ Ba an exothermic or endothermic reaction?

**H _{2}SO_{4} + Ba is an exothermic reaction because heat is liberated on addition of sulphuric acid.**

**Is H**_{2}SO_{4} + Ba a redox reaction?

_{2}SO

**H _{2}SO_{4} + Ba is not a redox reaction because only Ba undergoes oxidation reaction.**

**Is H**_{2}SO_{4} + Ba a precipitation reaction?

_{2}SO

_{4}+ Ba a precipitation reaction?

**H _{2}SO_{4} + Ba is a precipitation reaction because insoluble barium sulfate precipitates down at the end of reaction.**

**Is H**_{2}SO_{4} + Ba reversible or irreversible reaction?

_{2}SO

_{4}+ Ba reversible or irreversible reaction?

**H _{2}SO_{4} + Ba is an irreversible reaction because the products formed BaSO_{4} cannot be changed back to the reactants.**

**Is H**_{2}SO_{4} + Ba displacement reaction?

_{2}SO

**H _{2}SO_{4} + 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.
