Question 21 A 0.28 mol sample of diprotic acid, H2A, is dissolved in 250 mL of water. The Ka1 of this acid is 1.0 x 10-5 and Kaz is 1.0 x 10-10, Calculate the concentration of A in this solution. a) 1.0 x 10-5 M b) 1.7 x 10-3 M c) 3.3 x 10-3 M d) 1.0 x 10-10 M e) 1.12 M Question 22 In the reaction: CuO(s) + CO2(g) CUCO3(s) a) Cu?* acts as a Lewis acid and CO32 acts as a Lewis base. b) 0? acts as a Lewis base and CO2 acts as a Lewis acid. c) 0? acts as a Lewis base and Cu2+ acts as a Lewis acid. d) Cuo is the Lewis acid and CuCO3 is its conjugate base. e) CO2 is the Lewis acid and CuCO3 is its Lewis base.
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.
