What is the ionic equation between AlCl3 and NaHCO3?

The two occur mutually reinforcingHydrolysis of double aqueous branches

Al3+ +3H2O Al(OH)3 +3H+HCO3- +H2O H2CO3 +OH- The mixing of the two will undergo a mutually reinforcing double hydrolysis, Al3+ +3HCO3- =Al(OH)3 3CO2

Reacts with water. Acidic oxides.

Most of them can be directly combined with water to form nakhic acid.

co2+h2o=h2co3

so3+h2o=h2so4

SiO2 cannot react directly with water to form H2SiO3.

Unstable acids can also be decomposed by heat and degraded to form acidic oxides.

H2CO3 = (heated) CO2 + H2O

H2SO4 = (heated) SO3 + H2O

The disadvantage of ALO2- hydrolysis anti-rent-sell argument should be ALO2-+H+ +H20=AL(OH)3

al3+ +3hco3-==al(oh)3↓+3co2↑

2al3+ +3co32- +3h2o===2al(oh)3↓+3co2↑

The chemical equation for the reaction of aluminum chloride and sodium hydroxide is:

When sodium hydroxide is small: AlCl3+3NaOH=3NaCl+Al(OH)3;

When sodium hydroxide is excessive: AlCl3+3NaOH=3NaCl+Al(OH)3, Al(OH)3+NaOH=Naalo2+2H2O, and the total reaction equation is AlCl3+4NaOH=3NaCl+Naalo2+2H2O.

The reaction of aluminum chloride with a small amount of sodium hydroxide will generate sodium chloride and aluminum hydroxide precipitation, and if sodium hydroxide is added after the pure addition of sodium hydroxide, the amphoteric hydroxide aluminum hydroxide will react with sodium hydroxide to form sodium aluminate and water.

The reaction of NaHCO3 with other substances is mainly the reaction of carbonic acid (HCO3-), and Na ions do not form precipitates or compounds that are stable in the solution before water, so there is no sodium in the ion equation (Na+).

hco3^- h^+ h2o + co2

hco3^- ca(oh)2 = caco3 + oh^- h2o

The chemical equation is: 3 Na2S + 2 AlCl3 + 6 H2O = 3H2S +2 Al(OH)3 +6 NaCl

The ionic equation: 3 s2- +2 al3+ +6 h2o = 3h2s +2 al(oh)3

The essence is the double hydrolysis of S2- and Al3+.

Because ionic compounds are compounds made up of cations and anions, while aluminum chloride is a covalent compound.

The charge number of aluminum ions is large, the ionic radius is small, and it has a strong polarization ability, while the chloride ion radius is large, the polarizability is very large, and it is easy to deform, so the polarization of the two occurs, and the ionic bond is polarized into a covalent bond, so aluminum chloride is a covalent compound.

The molecules of covalent compounds are formed by the sharing of electron pairs between atoms. When two non-metallic element atoms (or inactive metal elements and non-metallic elements) are combined, one or more electrons are produced between the atoms to form an electron pair, which is attracted by the nuclei of the atoms of the two elements, which are common to the atoms of the two elements, so that the atoms of the two elements form compound molecules.
