Direct link to Krishna Phalgun's post Metals like potassium and, Posted 8 years ago. The higher the concentration of hydroxide ions from base molecules, the higher the pH of the solution and, consequently, the higher its basicity. Since a very strong acid has a very weak conjugate base, the chloride ion don't really take protons from water, thus it does not affect the pH of the solution, we thus do not include it into the equation. In this case, it does not. Benzoic acid (C 6 H 5 COOH) and aniline (C 6 H 5 NH 2 ) are both derivatives of benzene.

Most bases are minerals which form water and salts by reacting with acids. of hydroxide ions, and if we know that, we can I think the 'strong base if weak conjugate acid' argument only really works if the conjugate acid is less acidic than water. There was no strong acid or strong base for the weak species to react with, so we knew that we only had to set up an aqueous equilibrium between the conjugate acid/base pair and use Henderson Hasselbalch to find pH. = 2.4 105 ). Distinguish if a salt is acidic or basic and the differences. Next comes the neutral salt KI, with a . Creative Commons Attribution/Non-Commercial/Share-Alike.
