Prelab Target PH 4 4 10 Weak Acid of Base Citric Acid Acetic Acid Sodium Hydrogen Carbonate Ammonia Sodium Hydrogen Phosphate 9 7 1) Your task is to design a buffer system using the above marked weak acid or base with the target pH, including both the substances and the amounts needed to make 200 mL of buffer. Show your work and results. pH = pka + log ((NH3/NH4Cl]) 959.25+log((NH3/NH4Cl]) -0.25=log((NH3/NH4Cl]) 10^-0.25=([NH3/NH4Cl]) .562=((NH3/NH4Cl]) 2) Write the equation for the equilibrium involved in this buffer. Kb=[NH4+][OH^-1/[NH3]
