Re: How does the presence of impurities/ slight impurities interfere ? How does the presence of slight impurities interfere with the formation of a crystalline solid ? i was bufled by a student's presentation on a crystal of 0.05% methylene blue with Barium nitrate crystal . can anyone tell me how the crystalline system change with the addition of impurities ? For example , a crystal of pure barium nitrate is cubic in shape and the crystal with 0.05% methylene blue produced an octahedral shaped crystal y is that so ? my student in his presentation stated that the crystal forms in this way : a few layers of an ionic lattice of Ba(NO3)2 will form first followed by the a " chains " of hydrogen bonded Methylene blue will settle onto the lattice resulting as fine ridges on the crystal surface . I am still buffled by Y such things happened . majority of the prof. i've asked were material physics majors and i specialised in chemical kinematics anyone out there with a chem major can help ? :)
