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...
In this chemistry experiment, you'll be learning how to find the concentration of an acid using titration with a weak base. By the end of this experiment you'll understand more about chemical reactions between acids and bases and the process of titration. ...
The strong acid/weak base amphoteric ion exchange fibers with different ratios of acidic and basic groups and different grafting percentages were prepared by grafting styrene and 4-vinylpyridine onto polypropylene fiber and then sulfonating with chlorosulphonic acid, under various reaction conditions,...

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...
