Ph of weak acid and weak base salt

Webinitially placed in water. Strong acids or bases have α values of 1.0 (or very close to 1.0), and weak acids and bases have much smaller values. To calculate α you must know the initial concentration of weak acid or weak base in solution, and the equilibrium concentration of either H 3O + or OH-. Consider a 0.010 M solution of acetic acid, HC ... WebEquilibrium in a Solution of a Salt of a Weak Acid and a Strong Base Determine the acetic acid concentration in a solution with [CH3CO2−] = 0.050 M [ CH 3 CO 2 −] = 0.050 M and [OH −] = 2.5 × × 10 −6M at equilibrium. The reaction is: CH3CO2− (aq) + H2O (l) ⇌ CH3CO2H(aq) + OH− (aq) CH 3 CO 2 − ( a q) + H 2 O ( l) ⇌ CH 3 CO 2 H ( a q) + OH − ( a q)
