A solution of acetic acid, HC2H3O2, on a laboratory shelf was of undetermined concentration. If the pH of the solution was found to be (2.62x10^0), what was the concentration of the acetic acid? The Ka of acetic acid is 1.7x10-5. Express your answer to three significant figures.
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. A solution of acetic acid, HC2H3O2, on a laboratory shelf was of undetermined concentration. If the pH of the solution was found to be (2.62x10^0), what was the concentration of the acetic acid? The Ka of acetic acid is 1.7x10-5. Express your answer to three significant figures.
2. Hydrofluoric acid, HF, unlike hydrochloric acid, is a weak electrolyte. What is the pH of a 0.072 M aqueous solution of HF? The Ka for HF is 6.8x10-4. You must solve the quadric equation for this problem. Express your answer to two decimal places.
