What property of a particular solute towards a solvent is necessary for recrystallization to occur?
The coolness of the solution causes recrystallization. This is because the solute becomes solid at a higher temperature than the solvent.
When a rock changes due to the surrounding pressure on all sides what has occured?
Metamorphism from recrystallization could occur.
How is recrystallization temperature related to the grain size?
Grain size would generally increase during recrystallization with time spent at optimal crystallization temperature.
How is the melting of an impure compound expected to change with recrystallization?
The melting point of an impure compound will become closer to that of the actual melting point of the pure substance with recrystallization of your mixture.
How does mineralisation occur?
They grow by heat and pressure. (metamorphism, recrystallization).
What property of a particular solute towards a solvent is necessary for recrystallization to occur?
The coolness of the solution causes recrystallization. This is because the solute becomes solid at a higher temperature than the solvent.
What is a sentence for recrystallization?
the magma or lava heats the rock it is in contact with, causing recrystallization
When a rock changes due to the surrounding pressure on all sides what has occured?
Metamorphism from recrystallization could occur.
Why is sodium chloride not suitable for recrystallization?
The crystallization/recrystallization of sodium chloride from water solutions is frequently used.
What is the importante of recrystallization?
For purification
What problems might occur if crystallization occurs too rapidly?
premature recrystallization will cause the %recovery of the the said sample to be significantly low since some of its substituents has already cooled down before it reaches the filtrate that is to be analyzed
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".
How do you make the cocaine hard rock?
Presumably by recrystallization.
What kind of rocks forms by recrystallization?
sedimentary rocks

How is the melting of an impure compound expected to change with recrystallization?
