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...
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, ...
Question: Describe strong acid/weak base and strong base/weak acid reactions.Write the net ionic equation for the reaction between nitrous acid and potassium hydroxide. Do not include states such as (aq) or (s).Is the reaction reactant- ...

Classify the acid and base as either a strong acid (SA), weak acid (WA), a strong base (SB), or weak base (WB): KOH. Classify the acid and base as either a strong acid (SA), weak acid (WA), a strong base (SB), or weak base (WB): HCl. ...
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. ...
strong acid cation exchangersweak baseThe gel diffusion kinetics of ion exchange on strong acid cation exchangers with the participation of a weak base is considered. The kinetics of benzocaine desorption from sulfonated polycalixarene and CU-23 30/100 sulfocationite has been experimentally studied. ...

Explain the terms "strong acid" and "concentrated acid." Are these terms interchangeable? What is the difference among the following: strong acid, weak acid, polyprotic acid? What does base strength and acid strength mean? What is strong about a strong acid. What is common to all acids?
