Which statement is true regarding the solubility of salts ionic solids in water?
Ionic solids typically have high solubility in water due to the strong attraction between the ions in the solid and the polar water molecules, which allows for the ions to dissociate and be surrounded by water molecules. However, the solubility can vary depending on the specific ions present and their interactions with water molecules.
Solubility of sodium bicarbonate?
Sodium bicarbonate is soluble in water, with a solubility of about 9 grams per 100 mL of water at room temperature. When dissolved in water, it dissociates into sodium ions and bicarbonate ions.
What is the effect of dielectric constant of water on the solubility of the ionic salt?
The dielectric constant of water affects the solubility of ionic salts by reducing the electrostatic forces between ions. A higher dielectric constant allows water to better surround and dissolve the ions, increasing solubility. Conversely, a lower dielectric constant reduces the solubility of ionic salts in water.
What does sodium hydroxide have a high solubility in water?
Sodium hydroxide has a high solubility in water because it is a strong base that readily dissociates into sodium ions (Na+) and hydroxide ions (OH-) in water. This dissociation allows sodium hydroxide to form a homogenous solution with water.
What information can be obtained from an ion solubility chart?
An ion solubility chart provides information on the solubility of different ions in water. It shows which ions will form a precipitate (insoluble compound) when mixed with certain ions in a solution. This can help predict the outcome of chemical reactions and determine the products formed.
Is actinium solubility in water?
Actinium is not very soluble in water. Its solubility is extremely low, with only a small fraction of actinium ions forming in a dissolved state in water.
What is solubility and dissociation in water?
Solubility refers to the maximum amount of a substance that can dissolve in a certain amount of solvent, typically water. Dissociation in water occurs when an ionic compound breaks apart into its individual ions when dissolved in water. This process allows the ions to move freely in solution.
Why is lead chromate not soluble in water?
Lead chromate has a low solubility in water due to the strong electrostatic forces between the lead and chromate ions, which hold the compound together in a solid form. These forces prevent the ions from separating and dissolving in water, resulting in poor solubility.
Why solubility of NaCl in water is greater than glucose.?
The solubility of a substance in a solvent is influenced by factors such as the nature of the solute-solvent interactions and the structure of the molecules. NaCl dissociates into ions (Na+ and Cl-) when dissolved in water, allowing for strong ion-dipole interactions with water molecules, which enhances solubility. Glucose, on the other hand, does not dissociate into ions, resulting in weaker interactions with water molecules and lower solubility in comparison to NaCl.
Ph may affect the solubility of ionic compounds?
Yes, pH can affect the solubility of ionic compounds by influencing the charge on the ions. For example, changing the pH can alter the solubility of metal hydroxides by affecting the balance between the ions and their solid form. This can result in precipitation or dissolution of the ionic compound.
How many times will the solubility of barium sulfate in a solution of H2SO4 concentration of 0.025 mol / l decrease compared to its solubility in pure water?
Barium sulfate, BaSO4, is a sparingly soluble salt. The solubility of a salt in water depends on the concentration of the ions present in the solution. The solubility of a salt can be affected by changes in temperature, pressure and the presence of other dissolved species. When sulfuric acid (H2SO4) is added to water, it dissociates into two hydrogen ions (H+) and one sulfate ion (SO42-). The H+ ions can then react with the BaSO4 to form Ba2+ and SO42- ions. BaSO4 (s) Ba2+ (aq) + SO42- (aq) The solubility of BaSO4 in pure water is low, but when a strong acid such as H2SO4 is added to the solution, the solubility of BaSO4 is decreased. This is because the H+ ions react with the Ba2+ ions to form an insoluble solid, BaSO4. The solubility of BaSO4 in a solution of H2SO4 concentration of 0.025 mol/L will decrease compared to its solubility in pure water, because the H+ ions from the H2SO4 are reacting with the Ba2+ ions to form an insoluble solid, BaSO4. In other words, the added H2SO4 makes it more difficult for the BaSO4 to remain dissolved in the solution. It's important to note that the solubility decrease will depend on the concentration of the acid, the temperature and the presence of other dissolved species.
Is Fe NO3 3 soluble and why?
Yes, iron(III) nitrate, Fe(NO₃)₃, is soluble in water. This solubility occurs because it is an ionic compound, and the nitrate ion (NO₃⁻) is highly soluble in water. When Fe(NO₃)₃ is dissolved, it dissociates into iron ions (Fe³⁺) and nitrate ions, which interact favorably with water molecules, facilitating its solubility.
