Sodium sulfate is highly soluble in water, but insoluble in most organic solvents. If you want to increase its solubility in water (as for any salt), you can heat the solution or remove one of the products (sodium ions or sulfate ions) from solution. I can't think of any insoluble sodium salts, but barium sulfate (BaSO4) is insoluble in water. Thus, adding barium chloride (or some other soluble barium salt) will remove sulfate from the equilibrium (due to BaSO4 precipitation) and increase the solubility of sodium sulfate.
When ammonium sulfate is added to a hydroxide solution, such as sodium hydroxide, it will undergo a double displacement reaction. Ammonium sulfate will react with the hydroxide ion to form ammonia gas and water, along with the corresponding sulfate compound. This reaction is exothermic and can release heat.
Heating the saturated solution of Copper sulfate will not form the hydrated copper sulfate crystals because only after cooling down the saturated solution of copper sulfate then only the crystals of the hydrated copper sulfate can be formed
When sodium hydroxide dissolves in water, it dissociates into sodium ions (Na+) and hydroxide ions (OH-). This process releases heat, making the solution warm. Sodium hydroxide is a strong base and is highly soluble in water.
Copper sulphate when mixed with a protein will turn purple if the amount of protein is sufficient enough in quantity to trigger the reaction. Planex1234 says; No offense but i think it is starch that turns dark blue - purple. Thetada says: the colour changes are arguably similar. Iodine solution goes blue/black in the presence of starch. The colour that sodium hydroxide / copper sulphate solution goes in the presence of protein is variously described as mauve / purple.
Heating the sodium sulfate solution helps to speed up the dissolution process, making the compound dissolve more quickly and thoroughly in the solvent. Additionally, heating can increase the solubility of sodium sulfate in the solution, ensuring that more of it can be dissolved.
Sulfuric acid and sodium hydroxide will undergo a neutralization reaction to form water and sodium sulfate salt. The reaction is exothermic, meaning it releases heat. The resulting solution will be neutral in pH.

Sodium Sulphate(NA2SO4)Sodium sulfate is the sodium salt of sulfuric acid. When anhydrous, it is a white crystalline solid of formula Na2SO4 known as the mineral thenardite; the decahydrate Na2SO4·10H2O has been known as Glauber's salt or, historically, sal mirabilis since the 17th century. Another solid is the heptahydrate, which transforms to mirabilite when cooled. With an annual production of 6 million tonnes, it is a major commodity chemical product.Sodium sulfate is mainly used for the manufacture of detergents and in the Kraft process of paper pulping. About two-thirds of the world's production is from mirabilite, the natural mineral form of the decahydrate, and the remainder from by-products of chemical processes such as hydrochloric acid production.
The reaction between sodium hydroxide and sulfuric acid produces sodium sulfate, water, and heat. This is a neutralization reaction where the strong base, sodium hydroxide, reacts with the strong acid, sulfuric acid, to form a salt (sodium sulfate) and water. This reaction is exothermic, meaning it releases heat as a byproduct.
To prepare Benedict's solution, dissolve copper(II) sulfate, sodium citrate, and sodium carbonate in water, then add distilled water to make a final volume. Heat the solution until it boils and let it cool before filtering. Adjust the pH to 12 with sodium hydroxide and store it in a dark bottle.
To find the heat of solution when potassium sulfate is dissolved in water, you can use Hess's law. This involves adding the heats of formation of the products and subtracting the heats of formation of the reactants. You can use the enthalpies of solution of potassium ions and sulfate ions to calculate the overall heat of solution for potassium sulfate.
if u have sodium chloride solution just heat it..water will get evaporated leaving only sodium chloride
When ammonium sulfate is added to a hydroxide solution, such as sodium hydroxide, it will undergo a double displacement reaction. Ammonium sulfate will react with the hydroxide ion to form ammonia gas and water, along with the corresponding sulfate compound. This reaction is exothermic and can release heat.
A white precipitate of sodium sulfate forms, along with heat being released due to the exothermic reaction between sulfur trioxide and sodium hydroxide. The reaction produces sodium sulfate and water as the final products.
To dissolve sodium sulfate, simply add it to water and stir until it is fully dissolved. Sodium sulfate is highly soluble in water, so it should dissolve easily without the need for additional solvents or heat.
