Which is more soluble in water sodium carbonate naphthalene or calcium carbonate?
Sodium carbonate is more soluble in water than calcium carbonate and naphthalene. Sodium carbonate is a water-soluble salt, while calcium carbonate is sparingly soluble in water, and naphthalene is insoluble in water.
How Make up a 7.5 percent solution of sodium carbonate in water?
To make a 7.5% solution of sodium carbonate in water, add 7.5 grams of sodium carbonate to 100 mL of water and stir until the sodium carbonate is completely dissolved. This will give you a 7.5% (w/v) solution of sodium carbonate.
What is the ionic equation of sodium carbonate?
nickel sulfate + sodium carbonate -> sodium sulfate + nickel carbonate
What species are present when sodium carbonate is placed in water?
When sodium carbonate is placed in water, it dissociates to form sodium ions (Na+) and carbonate ions (CO3^2-). These ions attract water molecules and hydrate, hence the presence of sodium ions and carbonate ions in solution.
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.
How would you separate water sodium carbonate and calcium carbonate?
To separate water, sodium carbonate, and calcium carbonate, you could first evaporate the water to leave behind the dry sodium carbonate and calcium carbonate. Next, you could use solubility differences to further separate the sodium carbonate and calcium carbonate; calcium carbonate is insoluble in water while sodium carbonate is soluble. So, you could dissolve the mixture in water, filter it to remove the calcium carbonate, and then evaporate the water to obtain the sodium carbonate.
What is the effect of sodium carbonate pH on the solubility of certain compounds?
The pH of sodium carbonate can affect the solubility of certain compounds by increasing or decreasing their solubility. This is because the pH can alter the charge of the compound, making it more or less soluble in water.
Can All carbonates are insoluble in water?
No, not all carbonates are insoluble in water. While many carbonates, such as calcium carbonate and magnesium carbonate, have low solubility, some, like sodium carbonate and potassium carbonate, are soluble in water. The solubility of carbonates generally depends on the metal ion they contain and the pH of the solution.
What effects has sodium carbonate on the solubility of the emulsion?

Are the solubility characteristics of magnesium carbonate and sodium carbonate the same?
I want to know the solubility of magnesium on its own, let alone thir compounds.
How could you separate nickel carbonate from sodium carbonate?
One way to separate nickel carbonate from sodium carbonate is by utilizing differences in solubility. Nickel carbonate is insoluble in water, while sodium carbonate is soluble. By adding water to the mixture and filtering, the insoluble nickel carbonate can be separated from the soluble sodium carbonate.
What are examples of solubility in substance?
Some examples of substances with high solubility are salt in water, sugar in water, and ethanol in water. Conversely, substances with low solubility include oil in water and carbon dioxide in water. The solubility of a substance depends on its chemical structure and the solvent it is placed in.
What is a solid product of the reaction between solutions of calcium chloride and sodium carbonate?
Calcium carbonate has a solubility of 0.0006g per 100g of water at standard temperatures so the precipitate formed will be that. Sodium Chloride is very soluble, with 35.9g per 100g of water.
Which is more soluble in water sodium carbonate naphthalene or calcium carbonate?
Sodium carbonate is more soluble in water than calcium carbonate and naphthalene. Sodium carbonate is a water-soluble salt, while calcium carbonate is sparingly soluble in water, and naphthalene is insoluble in water.
How do you determine whether sodium carbonate is present?
Sodium carbonate can be identified by performing a flame test, which results in a yellow flame. Additionally, you can conduct a simple solubility test by dissolving the compound in water, which will result in a basic solution due to the presence of the carbonate ion. Finally, you can confirm the presence of sodium carbonate using analytical techniques such as titration with acid to determine the sodium carbonate concentration.
How is anhydrous sodium carbonate converted to pure hydrated sodium carbonate?
Anhydrous sodium carbonate can be converted to hydrated sodium carbonate by simply adding water. When anhydrous sodium carbonate reacts with water, it forms hydrated sodium carbonate through a hydration reaction where water molecules are incorporated into the crystal structure, resulting in a hydrated form of the compound.
