Chemistry 5. You melt the substance and de-coloration occurs. Unfortunately, you weren’t paying attention and miss the melting point. Should you start over or re-melt it? Or both are options ‘okay’? 6. When measuring the melting point of a substance, it suddenly disappears. What has happened? Can you still measure the melting point? If so, how? 7. We should not re-use a sample in a capillary tube for melting point measurement. Why not? 8. It takes significant amount of time for the melting point apparatus to cool down before next measurement if your new sample has a lower melting point than your previous one. What can you do to reduce this time in between measurements when many samples of different melting points are used?
