A buffer solution contains 0.31 mol of phenol (HC6H5O) and 0.85 mol of sodium phenoxide (NaC6H5O) in 4.00 L. The Ka of phenol (HC6H5O) is Ka = 1.3e-10. (a) What is the pH of this buffer? pH = _______ (b) What is the pH of the buffer after the addition of 0.27 mol of NaOH? (assume no volume change) pH = ______ (c) What is the pH of the original buffer after the addition of 0.62 mol of HI? (assume no volume change) pH = _______
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.
