Following teacher's guidance, one of the long bone was placed in a beaker containing vinegar (7% acetic acid), a weak acid and let it sit for 3 days at 370 C in an incubator. The other long bone was left in beaker containing distilled water and placed in the same incubator. The students were very curious - on the 4th day, they used gloves and removed the bones from respective jars with utmost care. The teacher asked them to write their observations (what happened) and the explanation (why did it happen) in the lab notebook in view of the structure-function relationship of bone. Assuming we are doing this lab activity. describe the observation in the vinegar treated long bone compared to the control set and explain what actually happened to justify observation
