On whether triacetin is the property of alkali
taste, alkali, its properties are more warm, in case of acid, it is harmonious, and has the ability to dissolve water, which can change the material. Now to distinguish whether triacetin is alkali, we should investigate its properties and characteristics in detail.

Triacetin has a unique quality. Looking at its shape, it may be a liquid under normal circumstances, clear and transparent, without pungent odor or special color. Smell, taste slightly fragrant, no alkali astringency.

In terms of its chemical properties, alkali contains more hydroxide ions, which can be released in water, making water alkaline. The structure of triacetin contains carbon, hydrogen and oxygen elements, and its bonding formula is very different from that of alkalis. In water, triacetin is difficult to release hydroxide ions, so it cannot make water alkaline.

Furthermore, it is verified with real evidence. Take a little triacetin, dissolve it in water, and measure it with a test paper. The color of the test paper does not show an alkaline color change. This is an empirical evidence that triacetin is not alkaline.

Another test is the sign of the reaction. When alkali and acid meet, it will neutralize, raw water and salt. If triacetin is mixed with acid, there is no sign of raw water and salt, and there is no sign of neutralization reaction.

In summary, triacetin is not alkali. Its properties, its quality, and its reaction characteristics do not match the characteristics of alkali. Therefore, it can be seen that triacetin does not belong to alkali, which is a definite theory.
