Complete the following table, which lists information about the measured acid dissociation constants of three unknown weak acids. Note: be sure each number you put in the table has the correct number of significant digits.
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.
According to Arrhenius concept, an acid is a substance i.e. when dissolved in water gives H+ ions . Thus Greater the number of H+ ions produced in the aqueous solution, the stronger is the acid.
Greater is the dissociation constant of the weak acid (Ka), greater is the amount of H+ (aq) produced, therefore stronger is the acid. Thus, Ka values give a measure of the relative strengths of the weak acids.
& Also pKa = - log ( Ka )
=> Higher the Ka value of acid , lower will be the value of pKa of acid
When comparing two compounds, the more acidic compound will have a higher Ka and a lower pKa.
