Of greater interest to us, you can use flowers and spices in much the same way a chemist uses commercial indicators in chemical titrations in the laboratory. A titration is the measured addition of a solution of known concentration into an another solution of unknown concentration with which it reacts, with the goal of reaching a proper end-point. And how does one know when the end-point has been reached? By…

Nice try, but “s” is not the correct answer. There is a difference and there is no difference between them. Both are correct.

Yes, we call it salt and we sprinkle it on our food. It enhances flavor to the palate. But to the chemist, it is merely one of thousands – millions of salts. So what is a salt to a chemist? It is one of two products (the other ordinarily water) of an acid-base reaction. Consider an example. An Example of a Salt Formation Calcium hydroxide plus sulfuric acid produces calcium sulfate plus water. Ca(OH)2 + H2SO4…
