Unformatted text preview: The solution was heated for approximately 30 minutes, and additional NaOH was added because the entire solution crystallized within the first 5 minutes. When solution volume had reached 4 mL, the solution was then cooled to room temperature and transferred to an Erlenmeyer flask. Water was added to dissolve the crystals, but the abundance of crystals had required its filtration from the solution. The acid, 10% H2SO4, was added drop wise, but the final pH was too high, at 2. The crude product was filter and recrystallized from ethanol-water. The melting point of the alcohol and the percent yield was determined. Write-up Questions 1. asdf 2. Sodium methoxide was stored under nitrogen in the buret to avoid water exposure. NaOCH 3 is very sensitive to water, and exposure will inhibit its function as a base catalyst. Water and NaOCH 3 also react to make methanol and NaOH. 3....
