Calculate the pH of a 1.0 M aqueous solution of sodium acetate at 25 degrees Celsius.
The first thing that you have to do here is to determine the equilibrium equation. We know that sodium acetate, NaCH3COOH, a weak base, breaks down into its component ions. Thus, when dissolved in water,
NaCH3COO Na+ + CH3COO-
Now the equilibrium equation is
CH3COO- + H2O ...
The solution shows clearly how to find the pH of this aqueous weak acid at room temperature using concepts from reactions at equilibrium.
