The method of preparation
Now there is a preparation, take forty milliliters of barbituric acid, the concentration is 0.1 mole per liter, and take forty milliliters of potassium hydroxide solution, the concentration is also 0.1 mole per liter. Mixing the two, the method of combining the two needs to follow the rules, pour slowly, and stir while pouring, so as to ensure uniform fusion.

Geibarbituric acid and potassium hydroxide are combined in the phase, and the reaction is delicate, which is related to the success or failure of the preparation. When the two are mixed, there may be changes in heat or changes in state of matter, so pay attention to observe. When the two are fully fused and let stand for a while, the required preparation can be obtained. This preparation may have different uses in the future, and its properties are also unique due to the combination of the two. When applying, it is necessary to carefully observe its properties and make good use of it.
