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, ...

Zn (OH)2 is a: a) strong base b) strong acid c) weak acid d) weak base. Acids, bases, and salts are called electrolytes because they dissociate into ions in water. Solutions of electrolytes conduct electricity because of the presence of ions (e.g. HCl -> H+ + Cl-) (a) Would ...
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...
Strong ions, weak acids and base excess: a simplified Fencl-Stewart approach to clinical acid-base disorders. Br J Anaesth. 2004 Jan;92(1):54-60.D. A. Story, H. Morimatsu, and R. Bellomo, "Strong ions, weak acids and base excess: a simplified Fencl-Stewart approach to clinical acid...
Weak Base and Strong Acid Titration 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 th...
Is {eq}HI {/eq} a strong acid, strong base, weak acid, or weak base? Acids and Bases: While the definition of acids and bases has been expanded by Lewis, there are no strong acids or bases that cannot be classified by the simplest definition of the Arrhenius classification of a...
Molecular shuttleThis Letter describes the base- and acid-mediated four-state (partially five-state) translational isomerization of a mixture of two [2]rotaxanes, each containing N-alkylamine and N-arylamine centers as binding sites for threaded crown ethers. Gradual changes in the molecular ...
