Synthesis of Salicylic Acid Lab Simulation
Students begin by typing in their name so it appears on their screen at all times. Students are walked through the steps of saponification to isolate salicylic acid. This includes requiring students to measure out and mix reagents, perform vacuum filtration, and using boiling and ice baths. A data table collects the information and provides assistance with performing the calculations to find percent yield. Although a simulation, it is designed to not give 100% yield and students will get differe
