Given the H3PO4 – NaH2PO4 buffer system, which of the following is false when KOH is added into the said solution? A. The concentration of the H3PO4 will decrease upon addition of KOH. B. The concentration of the H2PO4- will decrease upon addition of KOH. C. The concentration of the H2PO4- will increase upon addition of KOH. D. The [H2PO4-]/[H3PO4] will decrease due to the neutralization of the added KOH.
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.
