In the pharmaceutical industry pH levels are maintained using biological buffers. Buffers play an important role in the stability and solubility of drugs. Aspirin, a weak acid, is one common drug that is buffered, otherwise, the acidic nature causes problems with people's stomach lining. MgO is a common additive to help buffer aspirin.

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.
