    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? [tex]\[HC_2 H_3 O_3 = 1.8*10^{ - 5} \][/tex]

    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.
