Question

Помогите решить цепочку : Al-Al2(SO4)3-Al(OH)3-Al(NO3)3-KAl(OH)4

Answer 1

2Al + 3H2SO4 -> Al2(SO4)3 +3H2
Al2(SO4)3 + H2O -> 2Al(OH)3 + H2SO4
Al(OH)3 + HNO3 -> Al(NO3)3 +H2O
Al(NO3)3 + KOH -> Al(OH)3 + KNO3

Answer 2

2Al+3H2SO4=Al2SO43+3H2
Al(OH)SO4 + 2 H2O = Al(OH)3 + H2SO4
Al2(SO4)3+3Ba(NO3)--> 2Al(NO3)3+3BaSO4
?

Answer 3

Chemical Reaction Steps:

The given chemical reaction chain is as follows: 1. Al → Al2(SO4)3 2. Al2(SO4)3 + 6H2O → 2Al(OH)3 + 3H2SO4 3. Al(OH)3 + KOH → K[Al(OH)4] 4. Al(OH)3 + KOH → KAlO2 + 2H2O

Step 1:

The first step in the given chemical reaction chain is the reaction of aluminum (Al) to form aluminum sulfate (Al2(SO4)3).

Al → Al2(SO4)3

This reaction represents the formation of aluminum sulfate from aluminum.

Step 2:

The second step involves the reaction of aluminum sulfate (Al2(SO4)3) with water to produce aluminum hydroxide (Al(OH)3) and sulfuric acid (H2SO4).

Al2(SO4)3 + 6H2O → 2Al(OH)3 + 3H2SO4

This reaction represents the formation of aluminum hydroxide and sulfuric acid from aluminum sulfate and water. [[2]](https://mzz.misis.ru/wp-content/uploads/2015/09/Himiya_3_vyvod.pdf)

Step 3:

The third step is the reaction of aluminum hydroxide (Al(OH)3) with potassium hydroxide (KOH) to yield potassium tetrahydroxoaluminate.

Al(OH)3 + KOH → K[Al(OH)4]

This reaction represents the formation of potassium tetrahydroxoaluminate from aluminum hydroxide and potassium hydroxide. [[7]](https://rep.bntu.by/bitstream/handle/data/76252/Himiya.pdf?sequence=1&isAllowed=y)

Step 4:

The final step involves the reaction of aluminum hydroxide (Al(OH)3) with potassium hydroxide (KOH) to produce potassium aluminate and water.

Al(OH)3 + KOH → KAlO2 + 2H2O

This reaction represents the formation of potassium aluminate from aluminum hydroxide and potassium hydroxide.

These steps outline the chemical reactions in the given chain.
