Question

Реакции ионного обмена. CaCo3+H2SO4-> ион. сокращ. BaCl2+H2SO4->

Answer 1

CaCO₃ + H₂SO₄ --> CaSO₄ + H₂O + CO₂
CaCO₃↓ + 2H⁺ + SO₄²⁻ --> Ca²⁺ + SO₄²⁻ + H₂O + CO₂↑
CaCO₃↓ + 2H⁺ --> Ca²⁺ + H₂O + CO₂↑

BaCl₂ + H₂SO₄ --> BaSO₄ + 2HCl
Ba²⁺ + 2Cl⁻ + 2H⁺ + SO₄²⁻ --> BaSO₄↓ + 2H⁺ + 2Cl⁻
Ba² ⁺ SO₄²⁻ --> BaSO₄↓

Answer 2

1)CaCo3+H2SO4=CaSo4+H2O+CO2(стрелка вверх)\(выделился газ)
CaCO3+2H(+)+ SO4(-)=CA(2+)+SO4(2-)+H2O+CO2(стрелка вверх)
CaCO3+2H(+)=Ca(2+)+H2O+CO2(стрелка вверх) 

Answer 3

Reactions in Ion Exchange

Ion exchange reactions involve the exchange of ions between two compounds. These reactions occur when ions in a solution are attracted to ions of opposite charge in a solid or insoluble compound. The exchange of ions can result in the formation of new compounds or the separation of ions from a solution.

Reaction: CaCO3 + H2SO4 -> Ion Shortening

The reaction between calcium carbonate (CaCO3) and sulfuric acid (H2SO4) can be represented as follows:

CaCO3 + H2SO4 -> CaSO4 + H2O + CO2

In this reaction, calcium carbonate reacts with sulfuric acid to produce calcium sulfate, water, and carbon dioxide. The calcium sulfate (CaSO4) formed is an insoluble compound and precipitates out of the solution. The water (H2O) and carbon dioxide (CO2) are the byproducts of the reaction.

Reaction: BaCl2 + H2SO4 -> Ion Shortening

The reaction between barium chloride (BaCl2) and sulfuric acid (H2SO4) can be represented as follows:

BaCl2 + H2SO4 -> BaSO4 + 2HCl

In this reaction, barium chloride reacts with sulfuric acid to produce barium sulfate and hydrochloric acid. The barium sulfate (BaSO4) formed is an insoluble compound and precipitates out of the solution. The hydrochloric acid (HCl) is a byproduct of the reaction.

Conclusion

In summary, the reaction between calcium carbonate and sulfuric acid produces calcium sulfate, water, and carbon dioxide, while the reaction between barium chloride and sulfuric acid produces barium sulfate and hydrochloric acid. Both reactions involve the exchange of ions and result in the formation of insoluble compounds.
