HCO3 precipitates with what ions are formed

Whether the hydrolysis reaction can be carried out completely depends on two factors:1Promote each other's degree of hydrolysis (including the influence of material nature, external conditions, etc.) 2Solubility of hydrolysate.

The common ion pairs that can undergo "double hydrolysis reaction" in middle school chemistry are: Al3+ and HCO3, CO32, HS-, S2-; Fe3+ and HCO3, CO32; NH4+ with SIO32-, etc. al3+ +hco3- +h2o===al(oh)3↓ +co32-

Fe3+ +HCO3- +H2O===Fe(OH)3 +CO32- Let's think about this question:

Will Al3+ encounter acid groups that are weaker than carbonic acid, such as clo-, SiO32-, AlO2-, etc., undergo a "double hydrolysis reaction"? Based on the above conditions, the answer is yes.

In fact, since the solubility of Al(OH)3 and Fe(OH)3 is very small, the acid group of acids that are slightly stronger than carbonic acid can also undergo a "double hydrolysis reaction" with Fe3+ and Al3+.

With Al3+ Fe3+ and other ions, it can be double hydrolyzed to obtain precipitation.

al3+ +hco3- +h2o===al(oh)3↓ +co32-

fe3+ +hco3- +h2o===fe(oh)3↓+co32-

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 bicarbonate ion is an acid bridge good group salt.

Socks contain hydrogen that can be ionized, which reacts with alkalis to form carbonate and water.

Carbonic acid is a weak acid, and its salts are associated with strong acids.

The reaction produces carbon dioxide.

See **:

HCO encounters alkali and becomes CO socks selling brother

HCO strikes oh co leakage h ohco becomes co when it encounters acid

hco₃⁻＋h⁺＝h₂o＋co₂↑

1.Correct formula:

HCO3 - +H2O = Reversible = H2CO3 + OH-2If the temperature changes:

hco3+h2o=h2o+oh-+co3↑3.If there is some kind of precipitated ion in the liquid, it is very likely that the silver will collide to form some kind of carbonate, but the temperature of the Huibo rock will also form a precipitate if the temperature changes with the previous time.

CH3COOH+H2CO3+H2S+HCO3- +HS- Ability of Counter Ions to Bind Hydrogen Ions.

There are five substances included in the equation you provided: acetic acid, hydroxide, hydrogen sulfide, bicarbonate, and sulfate ions. Acetic acid (CH3COOH) is a weak acid that can donate hydroxyl (OH-) ions but not hydrogen ions (H+). Bicarbonate vertical oxide (H2CO3) is a neutral substance that provides both hydrogen ions and hydroxyl ions.

Hydrogen sulfide (H2S) is a weak base that can provide hydrogen ions but not hydroxyl ions. Ecosock orthosate (HCO3-) is an alkaline substance that can provide hydrogen ions and hydroxyl ions. Sulfate ion (HS-) is a weak base that can provide hydrogen ions but not hydroxyl ions.

Based on this information, we can conclude that acetic acid does not provide hydrogen ions and hence has a weaker ability to bind hydrogen ions to the corresponding ions. Both hydroxide and bicarbonate can provide hydrogen ions, so the corresponding ions have a strong ability to bind hydrogen ions.

Both hydrogen sulfide and sulfate ions can provide hydrogen ions, but since they are both weak bases, the ability of the corresponding ions to bind hydrogen ions is moderate.

each reaction. All have a reaction equilibrium constant.

The greater this constant, the more thoroughly the reaction will proceed.

Hydrolysis reinforces each other".

It is synthesized by two hydrolysis reactions, cation and anion.

The equilibrium constants of "mutual promotion reactions" = the product of the equilibrium constants of the two hydrolysis reactions.

The hydrolytic equilibrium constant of Al3+ is greater than that of NH4+.

When the anions are the same.

The equilibrium constant of Al3+ and anion hydrolysis is greater than that of NH4+ and the same anion.

The response is more thorough.

HCO3-+OH-=CO32-+H2O, bicarbonate is a conjugate base of carbonic acid and a conjugate acid of carbonate ions. The atomic arrangement of bicarbonate (HCO3-) is planar with carbon in the center and is bonded to three oxygen atoms (one C=O, one C-Oh, and one C-O-).

Both carbonate and bicarbonate are ions, and they are weak acid ions, both of which are easy to exist under alkaline conditions, and the acidity of carbonate deficiency root is weaker than that of bicarbonate, so it is easier to hydrolyze, so the alkalinity of the aqueous carbonate solution is stronger than that of the aqueous solution of bicarbonate. The degree of hydrolysis of carbonate ions is large, most of the salts bound by bicarbonate are soluble salts, and many salts bound by carbonate ions are insoluble clusters, and bicarbonate can be combined with hydroxides to form carbonate and water. Bicarbonate and carbonic acid do not collapse together, if the reaction of bicarbonate loses an h to become carbonic acid, carbonic acid gets an h to become bicarbonate, which is the same as no reaction.

Bicarbonate reacts with acetic acid and phosphoric acid, and phosphoric acid is a moderately strong acid.
