Prepare a concentrated stock solution of the standard by weighing the solute and transferring it to a volumetric flask with solvent.See this step-by-step guide for making aqueous solutions. Step 2: Make the standards for the calibration curve Perform a serial dilution Label a series of volumetric...
Which is more accurate burette or volumetric flask? Volumetric GlasswareVolumetric pipets, flasks and burets are the most accurate; the glassware makers calibrate these to a high level of accuracy. ... Class A volumetric glassware has a lower tolerance than Class B; for class A, the tolerance ...
Add 1 ml of 100 mM EDTA. Bring the volume up to 100 ml with a volumetric flask and store at 2-8°C. Ideally, protease and phosphatase inhibitors should be added on the day of use (100 μl each of aprotinin, leupeptin, and pepstatin; 500 μl each of PMSF, Na3VO4, and NaF). ...

To prepare 1 L of 0.5 N HCl solution, you have to take 0.5 gram equivalent of pure HCl. 1 gram equivalent of HCl = 1 mole of HCl. So, 0.5 gram equivalent HCl = 0.5 mole HCl = (0.5 x 36.5) gram HCl = 18.25 g HCl. Take 1 L volumetric flask. Pour 18.5 g HCl in it. Add ...

One of the most important properties of activated carbon is its ability to regenerate, i.e., the adsorbed substance is removed from the activated carbon to use it again [1,2,3]. This is carried out with the process of desorption, by reducing the pressure or increasing the temperature. How...
When I pointed out that many readers looking for a good cup of coffee might not go the distance of investing in and using a gram scale, Manson reluctantly agreed to provide a volumetric measurement: 1 tablespoon for 3 fluid ounces of water. For the 34-ounce French press I use daily, th...
