Homework Help: Chemistry 102

Posted by Nick on Monday, May 3, 2010 at 11:32am.

For a question like “calculate the pH of an aq.solution that is 1.0 M CH3COOH and 1.0 M CH3COONa, how do you know to write the equation like this: CH3COOH + H2O => H3O+ + CH3COO- and not like H3O+ + CH3COO- => CH3COOH + H2O for the ICE chart. This would switch the reactants and products.

Like “calculate pH of soln that .25M CH3COONa how do you know to do CH3COO- + H2O => CH3COOH + OH- and not the other way?
