A 1.00 liter solution contains 0.39 M nitrous acid and 0.51 M sodium nitrite. If 0.260 moles of potassium hydroxide are added to this system, indicate whether the following statements are true or false. (Assume that the volume does not change upon the addition of potassium hydroxide.) _______ A. The number of moles of HNO2 will decrease. _______ B. The number of moles of NO2- will decrease. _______ C. The equilibrium concentration of H3O+ will increase. _______ D. The pH will decrease. _______ E. The ratio of [HNO2] / [NO2-] will remain the same.
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.
