Ionic Equilibrium

Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.

Arrhenius Acid

Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.

Bronsted Lowry Base In Inorganic Chemistry

Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.

Question

Tutorial Problem for Weak Base and Strong Acid
You are given an Erlenmeyer flask containing 100.00 mL of 0.100 M B¯ and a buret containing 0.100M HCI. B¯ is a weak acid with a K of 5.9 x 10 º. Calculate the pH of the solution (to 2 decimal
places) after titrating the following volumes of HCl:
What is the pH after 0.0 mL HCI is added? 4.0
At this point no strong acid has been added, so you need to solve a weak base pH problem.
What volume of HCI is added at the equivalence point (to 0.1 mL)? 49
mL
What is the pH at the equivalence point? 49.
At this point no strong acid or weak base remains, so you need to solve a weak acid pH problem for the weak base's conjugate acid.
What is the pH after 50.0 mL HCl is added? 49
You are in the buffer region here. You need to find the relative ratio of [B-]/[HB]. Make sure to convert K, into K, before using the Henderson-Hasselbalch equation.
a
