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.

CHE 100-Lab 6 - pH
Lab 6-pH
Purpose: Obtain an understanding of acids and bases by seeing the information provided by
pH. Relate pH to [H₂O*].
Background information:
The pH of a substance is a measure of the concentration of H3O* (often abbreviated as
H). The higher the H* concentration, the lower the pH of the substance. A pH meter. detects H*
in a solution and calculates pH. In order to get accurate readings, the pH meter has to be
calibrated properly using solutions of known pH.
Part A - Strong and Weak Acids
1) Strong vs weak acids
a Determine the pH of 0.1M HCI (strong acid)
6) Determine the pH of 0.1M acetic acid (weak acid)
Impact of dilution
pH = -log [H]
In part A of this experiment, you will look at: (1) the difference between the pH of strong
and weak acids and (2) the impact of dilution on pH. In part B, you will look at: (1) the pH of basic
solutions and (2) how pH changes during acid/base reactions.
