Magnetic stirrers are often used in chemistry and biology, where they can be used to stir hermetically closed vessels or systems without the need for complicated rotary seals. They are preferred over gear-driven motorized stirrers because they are quieter, more efficient, and have no moving external parts to break or wear out (other than the simple bar magnet itself). Magnetic stir bars work wel… WebThink about your result. 0.25 L ( 250 mL) of the stock HNO 3 needs to be diluted with water to a final volume of 8.00 L.
