The investigation of the melting point of a substance
The physical properties of the world are very wonderful. Today, there is a substance whose melting point is quite important. This substance is chemically called Barbituric Acid.

If you want to explore the melting point of Barbituric Acid, you must first understand the reason and follow the method. Melting, the change of a substance from solid to liquid. Melting point, that is, the temperature at which the solid-phase liquid phase coexists in equilibrium under a certain pressure.

To measure the melting point of Barbituric Acid, you need a sophisticated instrument. Such as a melting point meter, its precision is related to the accuracy of the result. Prepare a clean capillary tube to hold the Barbituric Acid sample, so that the sample is packed tightly and evenly, and there should be no gaps, which will cause uneven heat transfer.

When measuring, first place the capillary filled with the sample in the melting point tester. Heat up at a suitable rate, do not be too hasty, if it is too hasty, the temperature change will be difficult to control, and the measured melting point will be too high; it should not be too slow. If it is too slow, it will take too much time, and the sample will be easily affected by the environment. Carefully observe the state change of the sample. When the Barbituric Acid initially appears as a droplet, record its temperature, which is the initial melting temperature; when the sample is completely melted into a liquid, record its temperature, which is the total melting temperature. Between the two is the melting point range of Barbituric Acid.

After several measurements and taking the average value, a more accurate melting point of Barbituric Acid can be obtained. In this way, the study of the melting point of Barbituric Acid is clear, which can provide an important basis for subsequent uses, such as chemical preparation, pharmaceutical research and development, etc.
