What is the concentration of calcium carbonate saturated solution?

The concentration of calcium carbonate in water is 8 at room temperature (25

Below, the solubility is 0

At room temperature (25), the concentration of calcium carbonate in water is 87 1029, solubility is 0 0014

The solubility of CaCO3 at 25 is , white precipitate.

There are no external conditions for temperature or something, how can you tell you?

Chemical properties of calcium carbonate.

1.Can react with acids: CaCO3 + 2HCl = CaCl2 + H2O + CO2

High temperature = CAO + CO2

3.It can react with water and carbon oxide in the biequilibrium calendar: CaCO3 + H2O + CO2 = Ca(HCO3)2

Carbonate is insoluble in water, so pH = 7,10, in case of dilute acetic acid, dilute hydrochloric acid, dilute nitric acid bubble boiling, and dissolve. When heated to 900 degrees in kilopascals, it decomposes into calcium oxide and carbon dioxide.

Caco CA + CO Calcium carbonate heated to 900 under a large air pressure will decompose into calcium oxide and carbon dioxide Caco + 2HCl CaCl + H O + CO Calcium carbonate will react with dilute hydrochloric acid, which will be effervescent to generate calcium chloride and water. 2,1.Can react with acids:

caco3 + 2hcl = cacl2 + h2o + co2↑

2.Pyrolysis: CaCO3 = High Temperature = CA + CO2

3.Can react with water and carbon dioxide: CaCO3 + H2O + CO2 = Ca(HCO3)2

Carbonate is insoluble in water, solubility product, so there is generally no aqueous solution of calcium carbonate,1,

Solubility of calcium bicarbonate at room temperature of 20 degrees?

Answer: Solubility of calcium bicarbonate in water g 100 ml (0 °C), g 100 ml (20 °C).

Calcium bicarbonate is an inorganic acid salt with the chemical formula Ca(HCO3)2, which is soluble in water.

Solubility of calcium bicarbonate in water:

g/100 ml (0 °c)

g/100 ml (20°c)

g/100 ml (40°c)

g/100 ml (60°c)

g/100 ml (80°c)

g/100 ml (100 °c)

Proper heating can improve solubility.

Calcium bicarbonate is relatively stable below 0 degrees Celsius; It is easy to decompose at room temperature to obtain calcium carbonate solids.

Calcium bicarbonate is an inorganic acid salt, calcium bicarbonate is a slightly soluble substance, and the solubility of calcium bicarbonate (pure water).

z denotes the number of protons or electrons gained or lost in the reaction of the substance.

c(1 z) represents the equivalent concentration; c denotes the degree of molar roll; n denotes the number of moles; v indicates the volume of the solution.

c（1/z）＝（n/z）/ v

c＝n/vc（1/z）＝（c*v/z）/ v

c（1/z）＝c/z

For example: kmno4 z 5 c(1 5kmno4) c(kmno4) 5

k2cro7 → z＝6 → c(1/6k2cro7)＝c(k2cro7)/6

CaCO3 is determined by the carbonate stool Zen dispersion coarse residual H2CO3 is equivalent to two protons.

When decomposed, H2CO3, H++, HCO3, H2O CO2

So. caco3 →ca+2＝2→c(1/2caco3）＝ccaco3/2

Summary. Calcium carbonate (CACO) is a compound composed of calcium ions (CA) and carbonate (CA). In a calcium carbonate molecule, the ratio of calcium ions to carbonate is 1:

1。Thus, when the concentration of carbonate is known, the concentration of calcium ions can be determined. The concentration of carbonate is known to be moles per liter (mol l), since the ratio of calcium ions to carbonate in calcium carbonate is 1:

1, so the concentration of calcium ions is also moles per liter (mol l).

Calcium carbonate (CaCo) is a compound composed of calcium ions (Ca) and carbonate (Co). In a calcium carbonate molecule, the ratio of calcium ions to carbonate is 1:1.

Thus, when the concentration of carbonate is known, the concentration of calcium ions can be determined. The concentration of carbonate is known to be mol per liter of silver (mol l), and since the ratio of calcium ions to carbonic acid in calcium carbonate is 1:1, the concentration of calcium ions is also mol per liter (mol l).

The solubility product constant of calcium carbonate is multiplied by 10 to the minus 9 power, so what is the concentration of calcium ions and carbonate?

The solubility product constant (ksp) of calcium carbonate (caco) is expressed as: ksp = ca ]co In this equation, [ca] is the concentration of calcium ions (ca) and [co is the concentration of carbonate (co. The solubility of calcium carbonate is known to be the product constant ksp = x 10.

Assuming that the degree of dissolution of calcium carbonate in water is s molar liters, then the calcium ion concentration and carbonate concentration are both s molar liters. Bringing these concentrations into the solubility product constant equation, we can get the trick of: ksp = s)(s) =s Substituting the known ksp value into the equation:

x 10 s Next, solve s:s = x 10 ) x 10 So, the concentrations of calcium ions and carbonate are both about x 10 mol liters in a saturated solution.

5 grams of hydrochloric acid, the first 40g of hydrochloric acid reacts with calcium carbonate, every 10g of hydrochloric acid reacts with 4g of calcium carbonate, the last 10g of hydrochloric acid does not react, and the last 4g is impurity and does not react.

Every 10g of hydrochloric acid reacts 4g of calcium carbonate, and the first 40g of salt spike acid is so, so the HCL contained in 10g of hydrochloric acid dust-dissolving mold solution is X, which corresponds to the slow reaction of 4g of calcium carbonate.

It can be carried with 20g of calcium carbonate stockings to react to the laughter surge.

Reaction equation: 2HCl + CaCO3 = CaCl2 + H2O + CO2

Chemical properties of calcium carbonate.

1.It can refer to the reaction of the land field with acid: CaCO3 + 2HCl = CaCl2 + H2O + CO2

High temperature = cao + CO2 traces.

3.It can react with water and carbon dioxide: CaCO3 + H2O + CO2 = Ca(HCO3)2

Carbonate is poorly soluble in water, so pH=7
