Show metadataprovide my evaluation of this resource in the recrytallization / melting point lab, there are a number of experimental details that need to be followed. choose whether the following statements are true or false.
the melting point apparatus should not be placed in a drafty location and should be protected from the effect of the room breeze.
in some melting point instruments, the sample is placed on a microscope slide which is then placed on top of a heated metal block, and the temperature of the metal block is raised until melting is observed.
if the sample to be melted were placed on a microscope slide then heated, finger oils on the microscope slide will lower the melting point.
a slow heating rate is necessary near the expected melting point if a mercury or alcohol thermometer is used in a melting point determination, a fractional degree reading should be possible with careful observation.
