Because the pK_a value cited is for a temperature of 25°C, we can use Equation 16.5.16: pK_a + pK_b = pKw = 14.00. Substituting the pK_a and solving for the pK_b, 4.83+pK_b=14.00.Since there is an equal number of each element in the reactants and products of 2CH3COOH + Na2CO3 = 2CH3COONa + H2O + CO2, the equation is balanced.
