Transferring the Solute Without Loss
The concentration of the final solution depends on every particle of the weighed solid reaching the flask. Weigh it on a watch glass, wash it into a beaker with distilled water, dissolve it and pour it through a funnel, then rinse the watch glass, beaker and funnel two or three times into the flask. Near the mark, hold a white card behind the neck so the meniscus shows clearly, and bring its lowest point level with the line while your eye is at the same height.
