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.

This problem involves the titration of a diprotic weak acid with a strong base. The neutralization reactions are:
Soluti
Н-СОЗ(аq) + КОН(аq) — к'"(аq) + НСО; (аq) + Н,0()
Guided So
HCO3 (aq) + KOH(aq) → K"(aq) + CO3² (aq) + H20(1)
The HCO3 and CO3 ions that result from this neutralization undergo hydrolysis as follows:
НСОЗ (ад) + Hә0() — Н-СО3(аq) + ОН (аq)
СОз (аq) + H20() — НСО; (аq) + ОН (аq)
Note: The potassium ion does not undergo hydrolysis and therefore does not impact the pH of the solution.
What are the K, values for H2CO3 and HCO3 ? How would you determine the K, values for HCO3 and
CO3?- from the values of Ka?
