My friend, I don't think what you want is the ionization equation, but the "ionic reaction equation" of these groups of substances reacting with each other, because most of what you wrote here is that it cannot be ionized, but ionic reactions can occur.
1.Sodium bicarbonate vs. nitric acid:
hco3-)+h+)=h2o+co2↑
2.Chlorine and water:
cl2+h2o=(h+)+cl-)+hclo3.Calcium carbonate and acetic acid:
caco3+2ch3cooh=(ca 2+)+2ch3coo-)+h2o+co2↑
4.Sodium peroxide and water:
2na2o2+2h2o=(4na+)+4oh-)+o2↑

Ionization equation.
nahco3=na+ +hco3-
hno3=h+ +no3-
You don't want ion equations???
cl2+h2o=hclo+h+ +clo-caco3+2ch3cooh=ca2+ +h2o + co2+ 2ch3coo-
2na2o2+2h2o=4na+ +4oh- +o2

Sodium bicarbonate and nitric acid: (HCO3-)+H+)=H2+CO2 chlorine and water:Cl2+H2O=(H+)+Cl-)+HCOcalcium carbonate and acetic acid:
caco3+2ch3cooh=(ca2+)+2(ch3coo-)+h2o+co2
Sodium peroxide and water: 2Na2O2+2H2O=2NaOH+O2

The equation for the ionization of sodium carbonate in water is: Na2CO3 = 2Na+ +CO32-.
Sodium carbonate ionizes in a very small amount in water, and the degree of hydrolysis is greater than the degree of ionization, and the hydrolysis equation is:
co3 2- +h2o = hco3- +oh-。
hco3- +h2o = h2co3 + oh-。
h2co3 = h+ +hco3-。
hco3- =h+ +co3 2-。
Introduction to Sodium Carbonate:
Sodium carbonate is an inorganic compound with the molecular formula Na2CO3 and molecular weight. The purity of chemicals is mostly above (mass fraction), also known as soda ash, but the classification belongs to salt, not alkali. Also known as soda or soda ash in international **.
It is an important inorganic chemical raw material, mainly used in the production of flat glass, glass products and ceramic glaze. It is also widely used in household washing, acid neutralization, and food processing.

Sodium bicarbonate ionization equation: NaHCO3=Na++HCO3-. There are two steps of ionization, the first step is ionization into Na+ and bicarbonate ions, and then the bicarbonate is partially ionized into H+ and carbonate ions.
Sodium bicarbonate decomposes easily when heated. Slowly decomposes in moist air. At about 50 the reaction begins to form CO, and at 100 all becomes sodium carbonate.
It is rapidly decomposed in weak acid, and its aqueous solution begins to decompose carbon dioxide and sodium carbonate at 20, and all decompose at the boiling point. The solution made of cold water without agitation only reacts slightly alkaline to phenolphthalein test strips, and its alkalinity increases when placed or raised at a higher temperature.

The ionization equation for sodium bicarbonate is: NaHC=Ionization=Na++HCO3
Sodium bicarbonate, chemical formula Nahco, commonly known as baking soda. White fine crystals, less soluble in water than sodium carbonate.
1. Equation for the reaction of sodium bicarbonate and acid.
Reaction with HCl: NaHCO+HCl=NaCl+HO+Co.
Reaction with Ch Cooh: NaHCO+CH COOH=CH Coona+HO+Co.
2. Reaction equation between sodium bicarbonate and alkali.
Reaction with sodium hydroxide: NaHCO +Naoh=NaCO+HO.
Reaction with calcium hydroxide: The dose of calcium hydroxide is divided into excess and small amounts.
NaHCO3) in small amounts: NaHCO+Ca(OH) = CaCo+NaOH+HO.
Overdose: 2NaHCO+Ca(OH) = NaHCO+CaCo+2HO.
3. Reaction equation between sodium bicarbonate and salt.

Reaction with CuSO4: basic copper carbonate and sodium sulfate are generated.
4. Sodium bicarbonate hydrolysis equation.
Double hydrolysis with aluminum chloride: 3NaHCO+ALCL ==AL(OH)3CO+3NaCl.
Double hydrolysis with aluminum sulfate: Al(SO)6NaHC==3NaSO+2Al(OH)6CO.
5. Sodium bicarbonate heating equation.

2.Preparation method:
1) Laboratory method: >>>More
Go to a certain sample.
After dissolving, excess hydrochloric acid is added to collect the gas produced to calculate the mol amount. >>>More
Because a large amount of hydroxide will be produced during hydrolysis, sodium bicarbonate will also be ionized to produce hydrogen ions, and hydrogen ions and hydroxide will be neutralized together, so the alkalinity is weak, and the pH value will become low. >>>More
Of course, the following methods are to measure the original mass in the sample, and then fully heat it to see how much the mass is reduced, and what is reduced is the H2O and CO2 released in 2NaHCO3=Na2CO3+H2O+CO2, so that the mass of NaHCO3 in it is known, and finally of course it must be converted into the original sample mass.
Sodium carbonate (soda ash) The chemical formula is Na2CO3, commonly known as soda ash, also known as soda and soda ash, an important chemical basic raw material, and the main product of the soda ash industry. It is usually a white powder, easy to decompose at high temperatures, soluble in water, and the aqueous solution is alkaline. Soda ash will deliquescent in humid air, slowly absorb carbon dioxide and water, and partially become sodium bicarbonate, so the packaging should be strict, otherwise it will absorb moisture and agglomerate, sodium carbonate and water will form Na2CO3·10H2O, Na2CO3·7H2O, Na2CO3·H2O three kinds of hydrates, of which Na2CO3·10H2O is the most stable, and the heat of dissolution soluble in water is very small. >>>More
