WebThe melting point of a substance is the temperature range over which the first crystal of a solid just starts to melt and the last crystal completes its melting. A melting point range is very narrow for pure solids (usually just 1 – 2 Co), and it is an intensive physical property – characteristic of the particular compound. WebThis whole experiment is based on purifying and then finding the melting point of the unknown compound. The theory is that if a substance is pure, it will have a very specific melting point, within one or two degrees Celsius. This is in opposition to a mixed, or contaminated substance, which will have a broad melting range.
