I have a chemistry B.S. and Ph.D. Some reactions don’t need to go to completion or are not expected to, like organic syntheses. In other cases it’s important to get the ratio of the reactants correct, otherwise you get precursor mixed in with your product. For baking you don’t want leftover baking soda, or flour, etc.
Please tell me about how your universities ran their chemistry labs then, because that’s how they were at every college i attended.
