Answer to Question #312451 in General Chemistry for Bead

Question

when the solution has been made up ,why is it necessary to mix the contents of the flask thouroughly? what feature of the volumetric flask makes this particularly necessary

Answer 1

Because the volume may change at mixing of a sample and a solvent, the sample should not be diluted directly to the marked line without stopping. After the final dilution, the solution is mixed thoroughly, by inverting the flask and shaking. The mixing is not enough when it is shaken without inverting.
