Determining the molarity of an unknown acid.

[Rick.45cal]

Dr. Farley, If I wanted to determine the molarity of a sample of an unknown acid. What would I need to set up an accurate (and relatively inexpensive) acid base titration? The molarity of the acid sample is likely fairly low.

Yes, that would be the way, assuming you thought it a strong acid like hydrochloric or sulfuric. Titrate until the pH rises above 7.

If its a weak one such as acetic, that's a little more complicated, but still the way.
