Solved: When Stirring Reactions, Why Is It Important To Us .

When stirring reactions, why is it important to use a stir bar rather than shaking the reaction vessel? 1.The reaction proceeds faster and more efficiently when using a stir bar. 2. Fewer side‑products are formed if a stir bar is used. 3. Shaking works just as well. There is no reason to use a stir bar. 4.
