How do you prepare 100 ppm fluoride standard from sodium fluoride?
To prepare a 100 ppm fluoride standard from sodium fluoride, you would dissolve an appropriate amount of sodium fluoride in a known volume of water. For example, to make 1 liter of 100 ppm fluoride solution, you would dissolve 0.1 grams of sodium fluoride in 1 liter of water.
How do you prepare 100 mM phosphoric acid?
To prepare 100 mM phosphoric acid solution, you can dilute a more concentrated phosphoric acid stock solution to the desired concentration by adding the appropriate volume of water. Calculate the volume of the stock solution needed using the dilution formula: C1V1 = C2V2, where C1 is the concentration of stock solution, V1 is the volume of stock solution needed, C2 is the desired concentration (100 mM), and V2 is the final volume of the solution.

How do you prepare 5mg percent working uric acid standard solution from stock uric acid standard solution?
Preparation of standards Prepare a stock uric acid solution of 100 mg/L. Dilute it to give working concentrations of 10, 20, 30, 40, 50 and 60 mg/L. Procedure:1 Prepare a 100 mg/L stock solution of uric acid Weigh out 100 mg uric acid, transfer it to a 1 L volumetric flash, add about 900 ml distilled water, and then add about 100 µl of 0.6 N NaOH to help dissolve the uric acid. Make up to the volume with water when uric acid is fully dissolved.2 Dilute the stock solution to give working concentrations of 10, 20, 30, 40, 50, 60 mg/L. To prepare 50 ml of the working standards 5, 10, 20, 30, 40, 50 mg/L respectively, weigh 10, 15, 20, 25, 30 g of stock solution into 50 ml volumetric flasks and make up to volume with distilled water.
How do you prepare 50 percent saturated solution?
To prepare a 50 percent saturated solution, first determine the solute's solubility in the solvent at the given temperature. For example, if the solute's solubility is 100 grams per 100 mL of solvent, you would dissolve 50 grams of the solute in 100 mL of the solvent. Stir the mixture until the solute is fully dissolved, and if needed, adjust the volume of the solution to ensure it remains at 100 mL. Always label the solution with the concentration and date prepared.
