Freezing Point Depression Constant Stearic Acid
There is a problem today, I want to study the freezing point reduction constant of a certain substance, with stearic acid as the main one. If the freezing point decreases the constant, the study of the behavior change of the substance is the most important. To observe the freezing point reduction constant of stearic acid, it is necessary to follow a scientific method to observe its change in detail.
Prepare an appropriate amount of stearic acid first, place it in an adapter, and observe its freezing state with the change of temperature. The urgency of temperature control, remember the change of temperature, and when stearic acid solidifies from liquid, measure its temperature precisely, which is its freezing point. Add other substances, miscible with stearic acid, and then measure the freezing point. After comparing before and after, calculate its constant according to the reason of freezing point reduction.
In the meantime, all kinds of operations must be careful, the cleanliness of the device and the accuracy of the quantity are all related to the accuracy of the number. Observing the drop of the freezing point and studying the properties of the lowering constant of the freezing point of stearic acid can provide a solid foundation for other studies, industrial and technical use, etc.
