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.

a. You do an equilibrium calculation to calculate the pH of a 0.1 M aspirin or
salicylc acid solution. I would use equation to calculate [H+] in this solution (C
= concentration of acid solution). The [H+] in the aspirin solution isthan the
[H+] in the salicylc acid solution because aspirin is a
acid than salicylc acid.
Ka = (C)/(x)(x) (blank 1)
Ka = x/C-x (blank 1)
Ka = (C-x)(C-x)/(x) (blank 1)
Ka = (x)(x)/(C) (blank 1)
