Question

Al2(SO4) добить четирими способами

Answer 1

2Al + 3H₂SO₄ = Al₂(SO₄)₃ + 3H₂

Al₂O₃ + 3SO₃ (t)= Al₂(SO₄)₃

2Al(OH)₃ + 3H₂SO₄ = Al₂(SO₄)₃ + 6H₂O

2Al(OH)₃ + 3SO₃ = Al₂(SO₄)₃ + 3H₂O

Answer 2

Chemical Reactions Involving Al2(SO4)3

Aluminum sulfate (Al2(SO4)3) can participate in various chemical reactions. Here are four ways it can react:

1. Reaction with Sodium Carbonate (Na2CO3): When aluminum sulfate reacts with sodium carbonate, the following reaction occurs: - Al2(SO4)3 + 3 Na2CO3 → 2 Al(OH)3 + 3 CO2 + 3 Na2SO4.

2. Reaction with Hydrochloric Acid (HCl): Aluminum sulfate can react with hydrochloric acid to form aluminum chloride and water: - KAlO2 + 4 HCl → KCl + AlCl3 + 2 H2O - NaAlO2 + 4 HCl → AlCl3 + NaCl + 2 H2O - NaAlO2 + 4 HNO3 → Al(NO3)3 + NaNO3 + 2 H2O - 2 NaAlO2 + 4 H2SO4 → Al2(SO4)3 + Na2SO4 + 4 H2O.

3. Reaction with Water (H2O): Aluminum sulfate can also react with water to form hydrated compounds: - NaAlO2 + 2 H2O → Na[Al(OH)4] - KAlO2 + 2 H2O → K[Al(OH)4].

4. Other Reactions: Aluminum sulfate can undergo various other reactions, such as reactions with magnesium (Mg), sulfuric acid (H2SO4), and more. For example: - Al2(SO4)3 + Mg → (reaction not specified). - 2 NaAlO2 + 4 H2SO4 → Al2(SO4)3 + Na2SO4 + 4 H2O. - 4 Mg + 5 H2SO4 → 4 MgSO4 + H2S.

These reactions demonstrate the versatility of aluminum sulfate in forming different compounds and products under various conditions.
