2 3 5 6 7 10 According to the background information in the lab writeup that you read, what are the sources of error in those filtration techniques ? the hose from the vacuum pump to the side-arm flask collapses when the filter paper becomes overloaded (meaning clogged). too much fluid is poured into funnel allowing the liquid and some solid to escape being trapped on the filter paper. the vacuum pump (negative) pressure is insufficient to complete the filtration. the filter paper used to trap the solid can rip allowing the solid to escape. the filter paper can become overloaded (meaning the pores in the filter paper become clogged) and filtration stops. the white solid (precipitate) disappears on the white filter paper.

Question Completion Status: 3 4 5 6 7 10 8 9 5 points Save A Question 10 Experiment #10: Question #2 - Synthesis of Strontium lodate Monohydrate (5 points) This chemical reaction between potassium iodate (KIO3) and strontium nitrate (Sr(NO3)2 results in a precipitate (a solid) being formed. The solid is retrieved by a filtration process, either gravity filtration or vacuum filtration (both shown below). These techniques were covered in the laboratory text and video materials.
