How can you prepare 50mm glucose?
To prepare a 50mm glucose solution, you would need to dissolve 9g of glucose in enough water to make 100mL of solution. This would give you a solution with a concentration of 50mm (millimolar).
How do you prepare chitosan solution?
To prepare a chitosan solution, dissolve chitosan powder in an acidic solution (such as acetic acid or hydrochloric acid) with stirring. Adjust the pH as needed and filter the solution to remove any undissolved particles. The concentration of the chitosan solution can be adjusted by varying the amount of chitosan powder used.
Prepare a working solution from a stock solution?
To prepare a working solution from a stock solution, you need to dilute the stock solution with a suitable solvent (such as water or buffer) to achieve the desired concentration. The equation C1V1 = C2V2 can help you calculate the volume of stock solution (V1) needed to make the desired volume of working solution (V2) at the desired concentration (C2). Always remember to mix the solutions thoroughly after dilution.
How can we prepare 1M solution of NaCl?
To prepare a 1M solution of NaCl, dissolve 58.44 grams of NaCl in water and dilute to 1 liter with water. This will give you a solution where the concentration of NaCl is 1 mole per liter.
How do you we prepare cresol with soap solution?
To prepare cresol with soap solution, add cresol to a container of water, then add soap and mix gently. The soap will help to solubilize the cresol in water, forming a soap solution with cresol dissolved in it. It is important to follow proper safety precautions when handling cresol, as it can be irritating to the skin and eyes.
How can prepare .01N KBr solution?
To prepare a 0.01N KBr solution, dissolve 0.74g of KBr in 1 liter of water. This will give you a solution with a molarity of 0.01N for KBr.
How do you prepare 0.2M of anhydrous of sodium thiosulphate?
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.
How would you prepare 1L of 000100 M Na2S2O3 starting with solid Na2S2O3 The numbers in Na2S2O3 are subscripts.?
first we calculate the molecular weight M.W=158.11 mass of Na2S2O3=M.W*concentration*volume(in litter) for a concentration of 0.001 mass of Na2S2O3=158.11*0.001*1=0.15811 g so we use this mass and continue the volume to be 1 L
How do you prepare 0.01N solution of sodium thiosulphate?
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.
Why do you use 25 grams to prepare 0.1N sodium thiosulfate solution?
To prepare a 0.1N solution of sodium thiosulfate, we need to weigh out 25 grams because each mole of sodium thiosulfate (Na2S2O3) is equivalent to 248.18 grams. Given that the formula weight is known, 25 grams gives the correct molarity of the solution.
How do you 0.02 sodium thiosulfate prepared?
To prepare 0.02M sodium thiosulfate solution, weigh out the required amount of sodium thiosulfate pentahydrate (Na2S2O3·5H2O) or anhydrous sodium thiosulfate (Na2S2O3). Dissolve this in distilled water and make up the volume to the desired concentration. Make sure to use a volumetric flask for accuracy and precision in preparing the solution.
How do you prepare 0.01n sodium thiosulfate as per ip?
To prepare 0.01N sodium thiosulfate per Indian Pharmacopoeia (IP) standards, dissolve 25.3 grams of pure sodium thiosulfate pentahydrate (Na2S2O3·5H2O) in distilled water to make 1000 ml of solution. This solution will have a normality of 0.01N.
How would the appearance of the solution change for each kinetic trial if the Na2S2O3 solution were omitted from the experiment?
If the Na2S2O3 solution were omitted, the appearance of the solution would not change significantly for each kinetic trial. Na2S2O3 is a reagent that acts as a reducing agent and is not directly involved in the appearance of the reaction solution. Its absence would likely affect the reaction rate rather than the visual appearance of the solution.
How do you prepare 0.002m sodium thiosulphate solution?
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.
What mass of na2s2o3 5h2o is needed to prepare 500.00 ml of 0.1000 m na2s2o3?
To calculate the mass needed, you first need to determine the molar mass of Na2S2O3•5H2O. Then use the formula: mass = molarity (M) x volume (L) x molar mass (g/mol). Substitute the values to find the mass of Na2S2O3•5H2O needed.
How many milliliters of 0.0200M Na2S2O3 solutions are needed to dissolve 0.450g of AgBr?
To find the amount of Na2S2O3 solution needed, first calculate the moles of AgBr using its molar mass. Then, use the stoichiometry of the balanced equation between AgBr and Na2S2O3 to determine the moles of Na2S2O3 required. Finally, use the molarity of Na2S2O3 to find the volume needed in milliliters.
Why water cannot be used to prepare sodium thiosulphate solution?
Water cannot be used to prepare sodium thiosulfate solution because sodium thiosulfate is not very soluble in water at low temperatures. This makes it difficult to dissolve the solid compound effectively in water to create a homogeneous solution. Warm water is usually required to increase the solubility of sodium thiosulfate.
