That mad the percent yield lower. There was also aspirin lost when it was taken from the filter paper and scraped into the 100 ml beaker, which made the percent yield lower as well. Another factor that could have influenced the loss of aspirin would be the possibility of too much ethanol being added to the solution, because it would upset the ratio and produce less aspirin. The final potential aspirin loss factor would be the changes of water temperature the solution was exposed to, which could have cause some to evaporate....
