What are the steps to prepare a standard solution?
A solution can be prepared by dissolving a known mass or volume of solute in a known amount of solvent. Concentration is expressed as grams of solute dissolved in one litre of solution. Example: Calculation for preparing 300 mL of a sucrose solution at a concentration of 5 g/L.What are the three steps in preparing a standard solution?
Solutions of known concentration can be prepared either by dissolving a known mass of solute in a solvent and diluting to a desired final volume or by diluting the appropriate volume of a more concentrated solution (a stock solution) to the desired final volume.
