H2SO4конц+HClH2SO4 конц+HBr​

Answer 1

Ответ:

H2SO4 + 8 HCl → H2S + 4 Cl2 + 4 H2O

H2SO4+ 8HBr---H2S+ 4 Br+ 4H2O

Answer 2

H2SO4 (конц) + HCl → H2SO4 (конц) + HBr

The reaction you've written is not balanced. I assume you want to know what happens when concentrated sulfuric acid (H2SO4) reacts with both hydrochloric acid (HCl) and hydrobromic acid (HBr).

When concentrated sulfuric acid reacts with hydrochloric acid, a displacement reaction takes place. The sulfuric acid is a stronger acid compared to hydrochloric acid, so it displaces it from the compound it's reacting with. The reaction can be represented as follows:

H2SO4 (конц) + 2HCl → SO2 + 2H2O + Cl2

In this reaction, sulfuric acid (H2SO4) reacts with hydrochloric acid (HCl) to produce sulfur dioxide (SO2), water (H2O), and chlorine gas (Cl2).

Similarly, when concentrated sulfuric acid reacts with hydrobromic acid, a similar displacement reaction occurs. The reaction can be represented as:

H2SO4 (конц) + 2HBr → SO2 + 2H2O + Br2

In this reaction, sulfuric acid (H2SO4) reacts with hydrobromic acid (HBr) to produce sulfur dioxide (SO2), water (H2O), and bromine gas (Br2).

It's important to note that these reactions can be highly exothermic and should be carried out with caution due to the release of corrosive gases and the potential for violent reactions. These reactions are typically performed in a controlled environment and under proper safety measures.
