As the pH of a substance rises from 7, it turns from a weak base to a strong base. A strong acid such as HCl, when mixed with water, will separate into molecules of hydrogen ions and chloride ions. That is called dissociation. Strong acids dissociate more completely than weak acids, ...
更新1: In this formular: eg of weak base: NH3 + H2O --- NH3+ + OH- Where did the another H+ went to?strong acid donates H+ and weak acid doesn't refuse to donate H+ weak acid also donates H+. no matter strong acid or weak acid when a substance in solu...

Weak Acid and Weak Base Titration Lesson Summary Frequently Asked Questions What happens when weak acid reacts with strong base? When a weak acid reacts with a strong base, the weak acid donates its hydrogen ion (H+) to the hydroxide ion (OH-) of the strong base. Once donated, water...
Ammonia is a ___. (a) Weak acid (b) Strong acid (c) Weak base (d) Strong acid (e) SaltStrong and Weak Bases:When you put a chemical species into the water and the species readily produce hydroxide ions, the species is a strong base. An example of...
To find the Kb of the weak base from the given Kh of the salt obtained from a strong acid and a weak base, we can use the relationship between Kh, Ka, and Kb. 1. Understanding the relationship: The relationship between Kh, Ka, and Kb is given by the equation: Kh=KwKb where Kw...
strong-acid/ weak-base, fabrication, structures, adsorption for amino ac- ids INTRODUCTION Among the ion exchangers, ion exchange fibers are the attractive materials for adsorption and separation. Compared with generally used granular ion exchange resins, ion exchange fibers exhibit high efficie...
The resulting membrane behaved as a charge-mosaic membrane at higher pH values and as an anion-exchange membrane at lower pH values, the behavior corresponding to the degree of dissociation of the carboxyl group. This weak acid-strong base type charge-mosaic membrane exhibited quite high ion ...
