    Hi, I was wondering which acid or base would be best to add to 25cm3 of distilled water to obtain solutions of pH 5, 6, 7, 8 and 9.

    Also which kind of concerntration? I'm going to add the acid/base drop by drop using a pH meter to read when it's at the correct pH. However, I'm not sure whether I need a strong or weak acid/base as well as what concentration.

    Thank you so much.
