1. Circle the volumes of the titrated NaOH(aq) which you want to use for your calculations. How and why did you choose these volumes of NaOH(aq)? 2. What is phenolphthalein and why is it required in this experiment? 3. What type(s) of reactions occurred in this titration? 4. (a) The sodium ion did not take part in this chemical reaction. What do we call such an ion? (b) Draw a simple diagram which shows how the sodium ion mixes with water in solution. What do we call this physical process?
