Question

Осуществить цепочку превращенийSO3 → H2SO4→ K2SO4→ BaSO4​

Answer 1

Ответ:

SO3 + H2O = H2SO4

H2SO4 + K2O = K2SO4 + H2O

K2SO4 + Ba(OH)2 = BaSO4 + 2KOH

Answer 2

Chain of Transformations: SO3 → H2SO4 → K2SO4 → BaSO4

To understand the chain of transformations from SO3 to BaSO4, let's break it down step by step:

1. SO3 → H2SO4: The first transformation is the conversion of SO3 to H2SO4. This reaction involves the addition of water (H2O) to SO3, resulting in the formation of sulfuric acid (H2SO4).

Equation: SO3 + H2O → H2SO4

2. H2SO4 → K2SO4: The second transformation is the conversion of sulfuric acid (H2SO4) to potassium sulfate (K2SO4). This reaction involves the reaction of sulfuric acid with potassium hydroxide (KOH), resulting in the formation of potassium sulfate and water.

Equation: H2SO4 + 2KOH → K2SO4 + 2H2O

3. K2SO4 → BaSO4: The final transformation is the conversion of potassium sulfate (K2SO4) to barium sulfate (BaSO4). This reaction involves the reaction of potassium sulfate with barium chloride (BaCl2), resulting in the formation of barium sulfate and potassium chloride (KCl).

Equation: BaCl2 + K2SO4 → BaSO4 + 2KCl

So, the complete chain of transformations is as follows:

SO3 → H2SO4 → K2SO4 → BaSO4
