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.

Question 3
Which of the following are NOT reasons we can't use water to recrystallize aspirin?
1. The aspirin is too soluble in water at room temperature.
II. The melting point of aspirin is too low.
III. The ester functional group on aspirin can be hydrolyzed in the presence of hot water,
converting the aspirin into a different molecule.
IV. The presence of the carboxylic acid group on aspirin makes its solubility highly pH
dependent.
