How do I find the freezing point? For example, in an experiment I used 10 grams of lauric acid and heated it and cooled it (Part A). Afterwards, I heated and cooled the same lauric acid (Part B). A question have is calculate the freezing point of lauric acid from Part A and Part B. How would I do this?
First of all the freezing point of the substance will not change, given that it has the same chemical composition thriughout.
If part A and Part B are both the same substances with same composition and concentration , their freezing points will be the same.
So now to calculate the freezing point of the acid , you can note down the temperature at which you see the freezing of the substance first,
Whenever the compound begins to freeze , it is the freezing point of the substance.
