WebThis podcast shows how to identify an acid or a base in a chemical reaction and what a strong acid-strong base reaction looks like. WebIn this model an acid is a proton (H +) donor and a base is a proton acceptor. In the Brønsted–Lowry model you cannot have an acid without a base, and vice versa; the acid has to donate its H+ to something (the base), and similarly the base has to accept it. The H + doesn’t just “drop off”—it is transferred. [3] rockabilly tee shirtsWebThe speed to the reactions may not be so easy to figure out, as to the rate determining steps.
