What mass of ammonium chloride should you add to 2.65 L of a 0.150 mol L-1 NH3 to obtain a buffer with a pH of 9.65? For ammonia, K. = 1.76 x 10-5. Express your answer in grams to two significant figures. v View Available Hint(s) > Hint 1. Calculate the concentration of ammonium chloride needed to obtain the desired (vm pH) of a buffer solution
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.
