Choose the correct statement about melting points. * Melting point can tell us if we have a mixture of compounds (for example, c

ompound of interest impurity). Melting point can tell us the identity of the components of a mixture. If we have a sample with a lowered melting range as compared to our standards, we can do mixed melting point determinations, combining our sample with each standard, to determine the identity of our sample. All of these are true. None of these are true.
