Amphetamine, C9H13N, is a potent central nervous system stimulant used in the treatment of ADHD and other disorders. The drug is also commonly abused for its stimulant properties. Amphetamine is a weak base with pKb=4.2. Amphetamine is frequently administered in the form of its hydrochloride salt, amphetamine hydrochloride (C9H13NHCl). Calculate the pH of a 0.150M solution of amphetamine hydrochloride.
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.
