Arsenic acid, a triprotic acid, has 3 pK a values (2.24, 6.96, and 11.50). What is the predominate form of arsenic acid at a pH of 4.00? a. A 3– b. HA 2– c. H 2 A – d. H 3 A e. The predominate form of arsenic acid cannot be determined from the given information
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.

Acidity is defined as the ability of a molecule to release protons. If a compound easily donate proton it is highly acidic. it depends on the stability of the conjugate base.
