Check the concentration of the (5) chemical species in solution (keep 3 significant number) when we dissolve 1.00g of sodium acetate (CH3COONa) in 35.0 mL of hydrochloric acid (HCl) at 0.050 M. Do not consider the effect of spectator ions on chemical equilibrium Ka (CH3COOH / CH3COO-) = 2.0 x 10-5 Question : With only the Ka of acetic acid, how do we find the concentrations of Na+ and Cl-? ***Na+ and Cl- come from CH3COONa and HCl which dissociate completely in water. Then, Na+ and Cl- do not participate in any reaction.
