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.

![Calculate the pH of a solution prepared by mixing 0.0870 mol of chloroacetic acid plus 0.0250 mol of sodium chloroacetate in
1.00 L of water.
First do the calculation by assuming that the concentrations of HA and A- equal their formal concentrations. The pK, of
chloroacetic acid is 2.865.
pH =
2.323
Then do the calculation with [HA] and [A-] from Equations 9-21 and 9-22.
[HA] = FHA – [H*]+ [OH¯]
