Experiment 3 Liquid-Liquid Extraction Discussion The success of extracting each compound out of the solution can be seen in the IR graphs for each substance. For ethyl 4-aminobenzoate‚ the N-H‚ C=O and C-O are distinguishable in their proper wavenumber positions. The amino N-H stretch was found between 3224 cm-1 and 3423 cm-1. The C=O was found at 1681 cm-1 and the C-O was at 1280 cm-1. The IR for benzoic acid also displays its significant bonds‚ O-H and C=O. The O-H was between 2566 and

Part A: Diffusion on a liquid in a liquid. I did an experiment with three different glasses of tap water from the faucet. All three cups measured the same which happened to be 13 cm from the top of the cup to the bottom of the cup. I let the water settle‚ and sit for about an hour so the temperature was the same for all three cups. I then placed one drop of food coloring into the first glass and waited for the coloring to reach the bottom. I calculated 93 seconds. I then went to the second glass

packed closely together‚ but they are able to move around. Hence a fluid does not have a rigid shape‚ but adapts to the contours of the container that holds it. Like a liquid a gas has no fixed shape‚ but it has little resistance to compression because there is enough empty space for the molecules to move closer. Whereas a liquid placed in a container will form a puddle at the bottom of the container‚ a gas will expand to fill the container. Although the three categories seem very well defined
