How to write the chemical equation of hydrolysis of alum dissolved in water?

The chemical equation for the hydrolysis of alum dissolved in water is: 2kal(SO4)2+3BA(OH)2=3BASO4 +2AL(OH)3 +K2SO4;

The chemical formula of alum is: kal(SO4).

Alum is aqueous potassium aluminum sulfate. Alum is an alum that has lost its crystalline water. It is a double salt of potassium sulfate and aluminum sulfate containing crystalline water. The chemical formula is kal(SO4)2·12H2O, and the adduct formula K2SO4·Al2(SO4)3·24H2O.

Potassium aluminum sulfate is a compound composed of two different metal ions and an acid ion, which can be ionized in water to produce two metal cations and sulfate ions.

Alum, also known as alum, potassium alum, potassium alum, potassium alum, potassium alum, is a double salt of potassium sulfate and aluminum sulfate containing crystal water. The appearance is often octahedral, or forms a polyshape with the cube, alum has antibacterial effect, and can be used as traditional Chinese medicine. It can also be used to prepare tanning materials, aluminum salts, paints, clarifiers, papermaking, mordants, baking powders, waterproofing agents, etc., and can also be used for food additives.

The chemical formula of alum is: kal(SO4) on the left side of the equation when encountering water kal(SO4)2K+Al3+

2so42-

It can ionize two metal ions in water: while Al3+ is easily water Al3+3H2OAL(OH)3(colloid)+

3H + Al3 + Ten 3H2O = = = Al(OH) 3 Ten 3H + Al(OH) 3 is colloidal, precipitated whole chemical equation: 2kal (SO4) H2O ===2 Al(OH) 3 [precipitation] K2SO4 3H2SO4

Alum dissolves in water to produce hydrolysis ion equation.

is: Al3+ +3H O = Al(OH) 3H+

The chemical equation is:

2kal(so₄)₂h₂o ==2al(oh)3↓＋k₂so₄＋3h₂so₄

Potassium aluminum sulfate dodecahydrate.

Also known as: alum, alum, potassium alum, potassium alum.

Potassium alum, which has been banned by the state for use in food additives, is a double salt of potassium sulfate and aluminum sulfate containing crystalline water.

Colorless cubic crystals, often octahedral in appearance, or with cubes.

The rhomboid-shaped dodecahedron forms a polymorphic shape, sometimes attached to the wall of the container and resembles a liquid-type hexagonal plate, which belongs to the type alum type of double salt, with glass luster.

Density, melting point. 9 molecules of crystal water are lost, and 12 molecules of crystal water are lost at 200, which are soluble in water and insoluble in ethanol.

Alum's taste is sour, leaky, cracked, and toxic.

The ionic equation for the hydrolysis of alum is: Al3+ +3H2O−Al(OH)3 + 3H+.

In daily life, alum kal(SO4)2·12H2O] can be used as a water purification agent, because alum is dissolved in water and undergoes hydrolysis reaction to generate aluminum hydroxide colloid, which can adsorb impurities.

Alum properties: Alum crystals are colorless or white octahedral crystals that are easily soluble in water, and their crystal structure belongs to the heteropolar trigonal crystal system. Its aqueous solution is acidic and can be used as an astringent, and sodium carbonate can be added to obtain "neutral alum".

When heated, alum will first dissolve in the crystal water contained in itself, and if it continues to be heated, it will lose its moisture to form an anhydrous white powder of aluminum potassium sulfate, which is called "burnt alum" or "burnt alum".

Alum. The chemical formula is: kal(SO4).

On the left side of the equation, when encountering water, kal(SO4)2 = k+ +al3+ +2SO42- It is combustible in water, and two metal ions are vertically separated by an electric plexus:

Whereas, Al3+ is easily water, Al3+ +3H2O = Al(OH)3 (colloidal) + 3H+

Al3 + Ten 3H2O = = = Al(OH) 3 Ten 3H + Al(OH) 3 is Pi Zheng dou colloid, precipitated.

The chemical equation of the whole.

2kal(SO4) H2O ==2AL(OH)3 [precipitation] K2SO4 3H2SO4

Alum is kal(SO4)2·12H2O, originally alum hydrolysis is reversible auspicious front 晌基 talk, once the front is hot, the reversible symbol is changed to "=".

ionic equation kal(so4)2= k+ +al3+ +2so42-; al3+ +3h2o = al(oh)3+ 3h+.

The total equation kal(SO4)2+ 3H2O = k++2SO42-+AL(OH)3+ 3H+

o^)/

Alum is kal(SO4)2·12H2O, which can be regarded as aluminum sulfate and potassium sulfate in Chenzhou, potassium sulfate is a strong acid and strong alkali salt, which does not participate in hydrolysis, aluminum sulfate is a strong acid deficiency and weak alkali poor brother salt, according to the principle of (who is weak who hydrolyzes, who is weak and shows who is sexuality), aluminum ion hydrolysis, equation: Al3++3H2O=Al(OH)3+3H+

2kal(so4)2·12h2o +6h2o=2al（oh）3+3h2so4+k2so4.

The hydrolysis equation of ammonium alum (NH4AL(SO4)2·12H2O) in Closed Water Laughing Qi is:

nh4al(so4)2·12h2o + h2o ↔ nh4+ +al3+ +2so4^2- +12h2o

In water, ammonium alum is decomposed into ammonium ions, aluminum car liter difference ions, and sulfate ions. This reaction is reversible, so these ions will be present in solution at the same time.

Alum is kal(SO4)2·12H2O, originally alum and Hui hydrolysis is reversible, once heated, the reversible symbol is changed to "=" ion square cherry answer program kal(SO4)2= k+ +AL 3+ +2SO42-; Al3+ +3H2O = Al(OH)3+ 3H+The total equation kal(SO4)2+ 3H2O = k++2SO42-+AL(OH)3+ 3H+
