Something that is soluble can dissolve in a liquid (like sugar in water), but something that insoluble cannot (like rocks in water). 11 people found this useful. have completed my Ph.D (organic chemistry), my research work was related to plants extraction and synthesis of isolated alkaloidal compounds, i isolated several alkaloids from plants as Cadabicine, cadabidine, Cadabicine ester etc. It is insoluble in water and all organic solvents but soluble in acidic solutions.
1 Bones and joints. 2  MRI can check for problems of the bones and joints, such as arthritis, problems with the temporomandibular joint, bone marrow problems, bone tumors, cartilage problems, torn ligaments or tendons, or infection. 3  MRI may also be used to tell if a bone is broken when X-ray results are not clear.
