Question

calculate the pH of 0.10M solution of alkaline, a weak base​

Answer 1

Answer:

Most acids are weak; there are hundreds of thousands of them, whereas there are fewer than a dozen strong acids. We can treat weak acid solutions in much the same general way as we did for strong acids. The only difference is that we must now take into account the incomplete "dissociation"of the acid. We will start with the simple case of the pure acid in water, and then go from there to the more general one in which salts of the acid are present. The latter mixtures are known as buffer solutions and are extremely important in chemistry, physiology, industry and in the environment. To keep our notation as simple as possible, we will refer to “hydrogen ions” and [H+] for brevity, and, wherever it is practical to do so, will assume that the acid HA "ionizes" or "dissociates" into H+ and its conjugate base A−.
