Question

Помогите, пожалуйста) Запишите реакции, укажите степени окисления (это не цепочка, просто отдельные реакции) Алюминий → алюминат калия оксид алюминия → алюминат калия гидроксид алюминия → алюминат калия алюминат калия → сульфат алюминия

Answer 1

Объяснение:

Алюминий → алюминат калия

2Al + 6KOH(расплав) = 2KAlO2 + 2K2O + 3H2↑

оксид алюминия → алюминат калия

Al2O3 + K2O = 2KAlO2

гидроксид алюминия → алюминат калия

Al(OH)3 + KOH(расплав) = KAlO2 + 2H2O

алюминат калия → сульфат алюминия

2KAlO2 + 4H2SO4 (избыток)= K2SO4 + Al2(SO4)3 + 4H2O

Answer 2

Reactions and Oxidation States

Here are the reactions you mentioned along with their corresponding oxidation states:

1. Aluminum → Potassium aluminate - Reaction: Aluminum reacts with potassium hydroxide to form potassium aluminate. - Oxidation states: The oxidation state of aluminum in this reaction is +3. - Source: [[1]]

2. Aluminum oxide → Potassium aluminate - Reaction: Aluminum oxide reacts with potassium hydroxide to form potassium aluminate. - Oxidation states: The oxidation state of aluminum in this reaction is +3. - Source: [[2]]

3. Aluminum hydroxide → Potassium aluminate - Reaction: Aluminum hydroxide reacts with potassium hydroxide to form potassium aluminate. - Oxidation states: The oxidation state of aluminum in this reaction is +3. - Source: [[3]]

4. Potassium aluminate → Aluminum sulfate - Reaction: Potassium aluminate reacts with sulfuric acid to form aluminum sulfate. - Oxidation states: The oxidation state of aluminum in this reaction is +3. - Source: [[4]]

Please note that the oxidation state of aluminum remains the same (+3) throughout all the reactions mentioned.

I hope this helps! Let me know if you have any further questions.
