The saturated solution of sodium chloride is 379,3 g for 1 kg solution at 8o oC.
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 prepare a 1% solution of sodium citrate, you would mix 1 gram of sodium citrate with 99 grams of water (for a total of 100 grams solution). Stir the mixture until the sodium citrate is fully dissolved in the water.
To prepare a 0.1N Na2S2O3 solution, dissolve 24.98 grams of Na2S2O3·5H2O (sodium thiosulfate pentahydrate) in distilled water and dilute to 1 liter in a volumetric flask. This will give you a 0.1N (normal) solution of Na2S2O3.
Dissolve 30-40 g of sodium chloride in 1 L of water.
To prepare a saturated sodium bicarbonate solution, add sodium bicarbonate (baking soda) to water until no more can dissolve. This creates a solution where the maximum amount of sodium bicarbonate is dissolved in the water.
Sodium thiosulphate solution (5-25 %)
To prepare a 0.01N solution of sodium thiosulfate, dissolve 2.48 grams of sodium thiosulfate pentahydrate (Na2S2O3·5H2O) in distilled water and make up the solution to 1 liter. This solution will be approximately 0.01N in strength. Remember to accurately weigh the compound and use a volumetric flask for precise dilution.
To prepare a 0.002M sodium thiosulfate solution, dissolve the appropriate amount of sodium thiosulfate pentahydrate (Na2S2O3·5H2O) in distilled water to make the desired volume of solution. Calculate the molarity using the formula M = (mol/L) and adjust as needed. Make sure to accurately measure and mix the components to ensure a homogeneous solution.
Dissolve 2.48818g of Na2s2o3.5h2o in frishly boiled distilled water. and add 2ml of chloroform for stability, it gives 0.01N sodium thiosulphate sol.
To prepare a saturated solution of sodium trioxocarbonate (IV), simply add the compound to distilled water at room temperature while stirring. Continue adding the compound until no more dissolves, indicating that the solution is saturated. This process ensures that the maximum amount of sodium trioxocarbonate (IV) is dissolved in the water.
Sodium thiosulfate is not conductive because it does not dissociate into ions in solution. It is a non-electrolyte.
To prepare 0.2M solution of anhydrous sodium thiosulfate (Na2S2O3), you dissolve 24.6g of anhydrous Na2S2O3 in distilled water and dilute it to 1 liter. This is the molar mass method, where molar mass of Na2S2O3 is 158.10 g/mol.
Yes, sodium thiosulfate is soluble in water. It dissolves readily in water to form a clear solution.
No, it is not correct.
In iodometry sodium thiosulphate is used because it is standardized by potassium dichromate and it is the best and relaible way to standardized sodium thiosulphate using iodometric titration. Infact sodium thiosulphate is also standardized by iodimetry. The difference between both of them is only of iodine. In iodometry iodine gas is liberated that will further react with sodium thiosulphate but in iodimetry standard solution of iodine is used.
Sodium thiosulphate is typically white in color, appearing as a crystalline powder or solid.
