Calculating Concentrations with Units and DilutionsHow to Calculate Concentration of a Chemical Solution

Calculating the concentration of a chemical solution is a basic skill all students of chemistry must develop early in their studi What is concentration Concentration refers to the amount of solute that is dissolved in a solventWe normally think of a solute as a solid that is added to a solvent eg adding table salt to water but the solute could easily exist in another phaseConcentration is an expression of how much solute is dissolved in a solvent in a chemical solutionThere are multiple units of concentrationWhich unit you use depends on how you intend to use the chemical solution The most common units are molarity molality normality mass percent volume percent and

Utility of concentration method by modified bleach protein determination by the biuret method

In the present study fine needle aspiration cytology FNAC was used to diagnose cases of tuberculous lymphadenitis We used the bleach concentration method on fine needle aspirates and compared the sensitivity of this technique in detecting AFB with that of routine ZN staining on FNA smearsThe principle of the biuret assay is similar to that of the Lowry however it involves a single incubation of 20 min There are very few interfering agents ammonium salts being one such agent and Layne reported fewer deviations than with the Lowry or
