SHOW ALL WORK
The neutralization of HC2H3O2 (aq) by NaOH (aq) can be considered to be the sum of the neutralization of H+ (aq) by OH- (aq) and the ionization of HC2H3O2. Write the net ionic equation for each of these reactions and demonstrate how two of them add together to yield the third. Using the data and Hess's law determine the enthalpy of ionization of HC2H3O2
Trial 1:
HC2H3O2: Average initnial temp. 21.7
NaOH: average initnal temp. 25
mixed at 4th mintue
5th-11th min temps: 29.7, 29.8, 30.1, 30.3, 30.5, 30.5, 30.4
Trial 2:
HC2H3O2: Average initnial temp. 22.4
NaOH: average initnal temp. 24
mixed at 4th mintue
5th-12th min temps: 30.0, 30.1, 30.5, 30.6, 30.8, 31.0, 31.1, 30.9
Explanation / Answer
CH3COOH --------------------> CH3COO- + H+
NaOH --------------------------> Na+ + OH-
H+ + OH- -------------------------> H2O
CH3COOH + NaOH -------------------> CH3COONa + H2O
