pH of 30ml 0.1M acetic acid mixed with 30ml 0.1M NaOH

[Pengwuino]

I have a question here and i don't really know how to do it.

I need to know : What is the pH of a mixture of 30ml 0.1M acetic acid and 30ml of 0.1M NaOH? $$\[HC_2 H_3 O_3 = 1.8*10^{ - 5} \]$$

I'm not even sure what the equilibrium equation would be! Any help would be appreciated.

Pengwuino, notice you have an acid (acetic acid) and a base (NaOH) .

• Initially, how many moles of each are there?
• When they react, what product will they form?
• How many moles of acid and base react, and how many moles of product is formed?
• So after, the reaction what happens to the product?

Figure out the answers to the above questions, and you are half way to the required answer.
