4. Get a dropper full of NaOH. Add drops of the NaOH one-by-one (count the drops) until one drop turns the solution pink and it stays pink. (swirl the flask while adding NaOH). 5. Record the total number of drops of NaOH needed to make the pink color stay pink. 6. Rinse the flask with tap water twice. Then rinse very well with DI water twice. 7.
