3. Vanadic acid is often used as a biological buffer when studying enzymes. You are asked to prepare 100.0 mL of a pH=9.17 buffer, but quickly realize you have only the following available to you: 3.0 M vanadic acid (H₂VOA), 1.0 g sodium dihydrogen vanadate (NaH₂VO4; MW=139.944 g/mol), 2.5 M disodium hydrogen vanadate (Na₂HVOA), and a full bottle of solid sodium vanadate (Na,VO; 183.9085 g/mol). Describe how you would prepare the buffer with the available chemicals. You also have all the water and plassware you want. Ko1 = 1.0 x 10, Ka2 = 2.8 x 10º and Kas = 5.0 x 10:¹5 for H₂VOA. Kw = 1.0 x 10¹4. H

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.
