why stoppered conical flask is used in the synthesis
Why volumetric flask should be stoppered after standard solution is prepared?
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.
Why is a pear shaped flask used in distillation?
