What is the melting point of compound Benzoin?
The melting point of compound Benzoin is approximately 135-137 degrees Celsius.
How is the melting of an impure compound expected to change with recrystallization?
During recrystallization, impurities are removed as the compound is dissolved and then slowly cooled to allow for the formation of pure crystals. As a result, the melting point of the compound should increase after recrystallization because the presence of impurities lowers the melting point of the compound.
What the composition of a melting point mixture?
A melting point mixture typically consists of a 1:1 ratio of the compound being tested and a known standard compound, such as benzoic acid. The mixture is heated slowly to determine the melting point range of the unknown compound. By comparing the melting point range of the unknown compound to that of the standard, the identity or purity of the unknown compound can be determined.
Does sugar affect melting point?
No, sugar does not affect the melting point. The melting point of a substance is determined by its chemical composition and structure. However, adding sugar to a solution can affect its boiling point, but that is a different property.
How you know specific compound from another by melting point?
Melting point is a unique characteristic of a substance.
How can one determine the melting point of a compound?
To determine the melting point of a compound, one can use a melting point apparatus. The compound is heated gradually until it changes from a solid to a liquid state. The temperature at which this change occurs is recorded as the melting point of the compound.
Is an alloy of aluminum has a melting range instead of a melting point is the alloy a compound?
It is a compound. All pure elements have a certain exact melting point.
How can a mixed melting point confirm the identity of an unknown compound?
The melting point is not enough to definitely identify the compound because different compounds may have a similar melting point range. It all depends on the compounds. If you have a compound of acetanilide and flourene, the results will lead to similar melting points of 115 degrees Celsius and 116 degrees of Celsius. The ranges will be similar so it would be hard to definitely identify the compound.

Why is it misleading to identify a solid compound just from a lone melting determination?
Identifying a compound based solely on its melting point is misleading because different compounds can have the same melting point. Additional tests, such as spectroscopic analysis or chromatography, are required to accurately determine the compound's identity. A single melting point determination is not sufficient as it could lead to a wrong conclusion about the compound present.
How is the melting point of an impure compound expected to change with recrystallization?
The melting point of an impure compound is expected to decrease with recrystallization. This is because impurities disrupt the crystal lattice structure, causing a broader melting point range. Recrystallization removes impurities, resulting in a purer compound with a higher melting point.
Does color affect a candles melting?
No, the color of a candle does not affect its melting point. The melting point of a candle is determined by the type and quality of wax used, not by its color.
Is the melting point of organic compound high or low?
Melting point is important in organic chemistry because it can be used for the identification of a compound. For pure solid organic compounds will have a small melting point range (0.5-10C),thus presence of impurity can also be find out by Melting point.
