Dissolve phthalic acid until saturated – a little bit of phthalic acid remains undissolved. 3. Pour the dissolved solution into four small test tubes and centrifuge for 2 minutes. 4. Pour all of the solution – from the four test tubes – into a 10mL graduated cylinder to measure the volume. 5. Weigh the small empty vial that will be used as a vessel for evaporation. 6. Add the solution to the vial and obtain the weight. 7. Heat up some water in a 150mL beaker. 8. Evaporate vial until no liquid remains. 9. Weigh the vial and its contents. 10. Leave overnight to dry and weight the vial and its contents again.
