Concept explainers

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.

1. Does your molarity of acetic acid agree with the percent of acetic acid present in the sample?
Use a calculation to determine this
2. At what pH does phenolphthalein turn pink? Do you think this causes an error in the
measurement of the equivalence point?
3. Describe how determining the titration of an unknown base with a known acid using
phenolphthalein as an indicator would differ from our titration today. Discussing the expected
changes in color would from phenolphthalein would be a good way to frame your answer.
