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...
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. ...
