The solubility of sodium chloride is 360,9 g/L at 20 0C; after this concentration the solution is supersaturated.
When an aqueous solution of BaCl₂ is added to an aqueous solution of Na₂SO₃, a double displacement reaction occurs, resulting in the formation of barium sulfite (BaSO₃), which is insoluble in water and precipitates out of the solution. The balanced chemical equation for this reaction is: BaCl₂ + Na₂SO₃ → BaSO₃ (s) + 2 NaCl. The precipitation of BaSO₃ indicates that a solid product is formed, while NaCl remains dissolved in the solution.
Yes, strontium chloride (SrCl₂) is soluble in water and exists as an aqueous solution when dissolved. In this form, it dissociates into strontium ions (Sr²⁺) and chloride ions (Cl⁻). Thus, when SrCl₂ is added to water, it readily forms an aqueous solution.
CuCl (copper(I) chloride) can be dissolved in water to form an aqueous solution, but it has limited solubility. When CuCl is added to water, it does not fully dissociate, resulting in a partially saturated solution. Therefore, while CuCl can exist in an aqueous form, it does not completely dissolve like more soluble salts.
The addition of a crystal to an aqueous solution can act as a seed for the precipitation of solute particles out of the solution through a process known as crystallization. This occurs when the crystal provides a surface onto which the solute particles can adhere and form a solid precipitate, causing them to come out of the solution.
When zinc metal (Zn) is added to an aqueous solution of hydrochloric acid (HCl), a chemical reaction occurs, producing zinc chloride (ZnCl₂) and hydrogen gas (H₂). The balanced equation for the reaction is: Zn + 2HCl → ZnCl₂ + H₂↑. The hydrogen gas is released as bubbles, and zinc chloride remains dissolved in the solution.

Yeast is added to the aqueous solution of glucose to convert it into ethanol through fermentation. Yeast enzymes break down glucose into ethanol and carbon dioxide.
An aqueous solution of borax will have a slightly basic pH. Litmus is a pH indicator that turns blue in basic solutions and red in acidic solutions. Therefore, when litmus is added to an aqueous solution of borax, it will likely turn blue.
The density of an aqueous solution is directly related to its composition. The more solute (substance dissolved in the water) that is added to the water, the higher the density of the solution will be. This is because the added solute increases the mass of the solution without significantly changing its volume, resulting in a higher density.
Calcium chloride. When carbonic acid is added to a solution containing calcium chloride, a white precipitate of calcium carbonate is formed due to the reaction of calcium ions with carbonate ions from carbonic acid.
Yes, strontium chloride (SrCl₂) is soluble in water and exists as an aqueous solution when dissolved. In this form, it dissociates into strontium ions (Sr²⁺) and chloride ions (Cl⁻). Thus, when SrCl₂ is added to water, it readily forms an aqueous solution.
Aqueous lead nitrate plus aqueous sodium iodide produce solid lead iodide and aqueous sodium nitrate.
You would need to add 18.75g of solid NaOH to the 750g of aqueous solution to obtain a 2.5% NaOH solution by mass.
A precipitate is expected to form when an aqueous solution of sodium sulfate is added to an aqueous solution of barium chloride. This reaction results in the formation of insoluble barium sulfate, which appears as a white precipitate.
