What is the salol experiment?
The Experiment Salol (phenyl salicylate) melts at about 45ºC and solidifies rapidly at room temperature. The sizes of the crystals formed are very different depending on the rate of the cooling. In this experiment, three small amounts of salol are placed on warm watch glasses and allowed to cool at different rates.
What is the relationship between crystal size and environment of formation?
The size of crystals in an igneous rock is an important indicator of the conditions where the rock formed. An igneous rock with large crystals probably indicates that the rock formed deep within the Earth, since it is typically warmer deep inside the Earth than near the surface.
How does temperature affect the cooling rate of crystals explain?
Temperature affects crystal size. The quicker a substance cools, the smaller the crystals will form because the molecules within that substance have a shorter time to arrange into a fixed, ordered pattern. have a crystalline structure because they cool quickly. 1.
What causes the different crystal sizes?
Explanation: The slower the crystals are formed the larger the crystals that are formed. Crystals that are formed near or on the surface tend to crystalize faster and therefore are usually smaller. Crystals deeper in the crust tend to crystalize slower and therefore are larger.
What is the melting point of Salol?

|---|---|
| ChEBI ID | CHEBI:34918 |
| Definition | A benzoate ester that is the phenyl ester of salicylic acid. Also known as salol, it can be formed by heating salicylic acid with phenol and is used in the manufacture of some polymers, lacquers, adhesives, waxes and polishes. |
What are the factors affecting crystal formation?
Variables that control crystal growth include the amount of dissolved material, evaporation, pressure and temperature. The higher the amount of dissolved material in the water and the more pressure that is placed on the material, the bigger the crystals will grow.
What are the factors affecting crystallization?
FACTORS AFFECTING CRYSTALLIZATION OF SUGARS Both the rate of formation of nuclei and the rate of crystallization are affected by the nature of the crystallizing substance, the concentration, the temperature, agitation, and the impurities present in the solution.
Why do crystals grow faster in cold temperatures?
Colder solutions contract, forcing minerals closer together, so they create bonds, catching impurities in their structure at the same time. These impurities interrupt the crystal pattern, forming a larger number of smaller crystals.

What is salol used for?
noun Pharmacology. a white, crystalline, aromatic powder, C13H10O3, produced by the interaction of salicylic acid and phenol, used as a preservative, a light absorber in suntan preparations, and in medicine chiefly as an antipyretic and as an antiseptic.
