When a solid is highly impure, this means that many different compounds are present apart from the solid, or that the compounds present are unknown. In order to perform recrystallisation, one needs to know what the impurities are or at least have an idea, since this technique involves choosing a solvent in which the solid wanted dissolves when the solvent is hot but recrystallizes back when the solvent is cold, while at the same time the impurities must dissolve in this solvent but remain dissolved in it. Therefore, unless the impurities are known or if there are many different impurities, a proper solvent cannot be chosen and recrystallization cannot occur

Why is it important for observations to be accurate?
A scientist must make accurate observations because usually these results are going to be communicated to others. Some people might even want to do the same experiment so you have to give the right directions before something bad happens. However, though, in experiments, scientists repeat their trails for more accurate results.
Why do scientists perform experiments after suggesting an answer to a problem?
An experiment is to carried out to analiysis the suggesting answer or we called it as a hypothesis is correct or not. This will give the scientist a more accurate answer towards the problem.
A measurement that is accurate is one that?
The measurement that is accurate is one that is precise. These are also commonly titled accurate measurements in the books.

How accurate are the Garmin fishfinders when there are waves?
Garmin fish-finders are very accurate. They are great products and the employees stand behind their products. They want you to have the best experience ever with their product.
Where is the nearest Apple Auto Glass located?
You need to give a specific location in order to allow for an accurate location. Because you did not provide where you are, you can go to their website and browse their locations and products.
How is recrystallization temperature related to the grain size?
Grain size would generally increase during recrystallization with time spent at optimal crystallization temperature.
What does it mean to oil out in recrystallization?
In recrystallization, oiling out occurs when the desired compound has a large impurity with it. Simply put, oiling out is when the product separates not as crystals, but as a liquid "oil".
