Some carbonates are soluble (carbonates of alkali metals) and some carbonates are practically insoluble in water (calcium and magnesium carbonate etc.).

Why carbonate salts are insoluble?

Carbonate salts are insoluble in water because of the strong ionic bond between the carbonate ion (CO3^2-) and the cation in the salt. This bond is difficult to break, preventing the salt from easily dissolving in water. Additionally, the carbonate ion tends to form insoluble precipitates with many cations, further reducing its solubility.


What happens to the solubility of salts when temperature is lowered or raised?

When temperature is lowered, the solubility of most salts decreases because the solubility of solids generally decreases with decreasing temperature. Conversely, when temperature is raised, the solubility of most salts increases as the solubility of solids typically increases with increasing temperature.


How the carbonate salts changes to sulfate salts?

Carbonate salts can be converted to sulfate salts through a double displacement reaction where the carbonate anion is exchanged with the sulfate anion. This reaction usually requires the addition of a sulfate-containing compound to the carbonate salt solution, leading to the formation of sulfate salts and a carbonate byproduct. The reaction can be represented by the general formula: (CO3)2- + SO4 2- → (SO4)2- + CO32-


Can magnesium carbonate be made as a precipitate by reacting together magnesium sulfate and calcium carbonate?

The proposed method of making magnesium carbonate can not be accomplished from solutions in water, because the solubility of calcium carbonate in water is so low that it can not furnish a sufficient concentration of carbonate ions to exceed the solubility product constant for magnesium carbonate.


What chemical system can Ksp be assigned?

Ksp, or the solubility product constant, is typically assigned to sparingly soluble salts that dissociate in water to form ions. This includes compounds like silver chloride (AgCl), lead iodide (PbI2), or calcium carbonate (CaCO3).

Do all salts hae the same solubility?

No, the solubility of salts can vary based on their chemical composition and structure. Factors such as temperature, pressure, and the presence of other substances can also influence the solubility of salts.


How does pH affect the solubility of calcium carbonate?

The solubility of calcium carbonate decreases as pH increases. This is because calcium carbonate is more soluble in acidic conditions and less soluble in basic conditions.


How does temperature affect solubility of salts?

Increasing the temperature the solubilty of salts in water is higher.

How the solubility of lithium carbonate can be incresed?

By increasing the pressure........


Why potassium carbonate cannot be prepared by solvay process?

Potassium carbonate cannot be prepared by the Solvay process because potassium salts are highly soluble in water, making it difficult to separate potassium carbonate from the solution produced in the process. The Solvay process is specifically designed for the production of sodium carbonate, which has different solubility properties compared to potassium carbonate.

How does the solubility of sodium carbonate in water change with varying temperatures?

The solubility of sodium carbonate in water increases as the temperature rises. This means that more sodium carbonate can dissolve in water at higher temperatures compared to lower temperatures.
