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.

In each box of the titration curve of a weak acid (HA) being titrated with a strong
base (NaOH) on the graph below, draw a particle diagram of the major species
found in the solution. Be sure to include a key indicating the symbols used for each
substance. Starting with four HA molecules and slowly adding NaOH, reflect what
will be present at each point on the titration graph for which there is a box.
а.
Determine the concentration of HA if a 50.0 mL sample of HA required 100.0 mL
