    Hi.

    I attempted question 4b and obtained a pH change of 6.71. However, the answer states that there is a pH change of 0.02. I know I must have done something wrong because the pH is only affected ever so slightly.

    Could someone attempt this question and explain how they obtained the answer.
    Thanks!
