Determine the quantity of sodium acetate (CH COONa) needed to create buffer solution at a particular pH. Do this by constructing an ICE table, writing the equilibrium constant expression, and using this information to determine the mass of starting material required. The value of Ka for CH COOH is 1.8 x 10%. Complete Parts 1-3 before submitting your answer. 1 2 NEXT > Sodium acetate (CH COONa) is added to an existing 500.0 mL solution of 0.200 M CH COOH to form a buffer with a pH equal to 5.000. Let x represent the concentration of CH COO in the water after the addition of CH COONa. Fill in the ICE table with the appropriate value for each involved species to determine concentrations of all reactants and products. Initial (M) Change (M) Equilibrium (M) CH,COOH(aq) + H₂O(1) = H_O^(aq) + CH,COO (aq)
