WebThe reaction 3 NaOH (aq) + H 3 C 6 H 5 O 7 (aq) → Na 3 C 6 H 5 O 7 (aq) + 3 H 2 O goes to completion and is suitable for analytical titrations. Part 1 is posted online at the Chem 13 News magazine website. WebNow onto the word equation. Potassium hydrogen phthalate reacts with sodium hydroxide. This means that realistically the sodium must react to make something with either the potassium, the hydrogen or the phthalate. Hydroxide will also have to react with one of those three things. There are a few basic reactions that you should know.
