Data Table 2: Mixture Summary
About 0.02% was recovered through the separation techniques.
1. What percent of the total mass of mixture of solids (Init ial) was recovered through the separation techniques?
Particles that didn't get separated completely or being lost on containers.
2. Describe possible sources of error to account for any deviation between the % of the total mass of mixture of solids (init ial) and the sum of separated components.
The most challenging step to perform in the separation procedure was separating the benzoic acid because it stuck to the sides of the cup. I ended up adding too much water to get as much of the benzoic acid as I could. This cause me to have to boil the salt solution longer than the experiment suggested. I'm not sure what could have been done to help this problem.
3. What was the most challenging step to perform in the separation procedure? What would you suggest to make the step less challenging?
