A student was titrating a solution of HC₄H₂ O₂ with a Sr(OH) ₂, solution. Determine the pH at a particular point in the titration. Do this by constructing a BCA table, constructing an ICE table, writing the equilibrium constant expression, and use this information to determine the pH. The value of Ka for HC₄​H ₇O ₂​ is 1.5×10⁴ .
