Question #66b60
1 Answer
Here's what's going to happen this time. The balanced chemical equation for your neutralization reaction was
Calculate how many moles of acetic acid and of sodium hydroxide you add together
Since you add equal numbers of moles of acetic acid and sodium hydroxide, both compounds will be completely consumed by the reaction.
In the process, the reaction will produce 0.0025 moles of acetate anions,
The acetate anion can act as a weak base and react with water to produce hydroxide ions and reform acetic acid according to the following equilibrium
To determine the concentration of the acetate anion, use the total volume of the solution, which is
This will get you
Use an ICE table to determine the concentration of the hydroxide ions in solution
I.......0.0500.............................................0.............................0
C........(-x).................................................(+x)..........................(+x)
E......0.0500-x..........................................x..............................x
By definition, the base dissociation constant,
Since
Since
The pOH of the solution will be
Therefore, the pH of the solution will be
