emistry A 110.0-mL buffer solution is 0.105 M in NH3 and 0.135 M in NH4Br. The Kb value for NH3 is 1.76x10-5. A) What mass of HCI can this buffer neutralize before the pH falls below 9.00? B) If the same volume of the buffer were 0.250 M in NH3 and 0.395 M in NH4Br, what mass of HCI could be handled before the pH falls below 9.00? I would appreciate any help. Thank you!
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.
