A solution of an unknown acid was prepared by dissolving 4.168 g of the solid acid in enough DI water to make 500.0 mL of solution. It takes 23.47 mL of 0.1678 M NaOH solution to neutralize 10.00 mL of the unknown acid solution.   Assuming that the acid is monoprotic. What is the concentration of the acid?

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.
