If the melting point is not exactly 113.7 ºC then it is not pure.
A desiccator is not typically used to dry acetanilide after crystallization because acetanilide is a relatively stable compound that can absorb moisture from the air, potentially affecting its purity. Moreover, using a desiccator may not effectively remove all the solvent used during crystallization, such as water or other volatile solvents. Instead, techniques like gentle heating or vacuum drying are preferred to ensure complete removal of impurities and solvents without compromising the integrity of the acetanilide.
The density of the sample is calculated by dividing the mass (160.0g) by the volume (15.0 mi^3), which results in 10.67 g/cm^3. The density of pure lead is known to be 11.34 g/cm^3, suggesting that the sample is not pure lead but likely a different material with a lower density.
A contaminated unknown sample could potentially introduce foreign material that may interfere with the identification process. This contamination could lead to misleading results or hinder the ability to correctly identify the unknown sample. It is important to ensure the sample is pure and free from contamination for accurate identification.
Yes, acetanilide is an amide. It is derived from aniline and acetic acid, containing the amide functional group (-CONH2).
To calculate the amount of pure silver in the sample, multiply the mass of the ore by the percentage of silver: 0.53 grams * 5.4% = 0.02862 grams of silver. To convert grams to milligrams, multiply by 1000: 0.02862 grams * 1000 = 28.62 milligrams of pure silver in the sample.
A possible reason for low yield in the bromination of acetanilide could be the presence of impurities in the starting material. Impurities can compete for reaction sites or react in unwanted ways, leading to lower yields of the desired product. It is important to start with a pure sample of acetanilide to maximize the yield of the bromination reaction.
No you cannot make a pure sample of Fluorine because it is an earth made element.
The sample could be described as pure gold or 100% pure gold.
the most suitable for recrystrallizing acetanilide is water..
Acetanilide can form eutectic mixtures with substances like urea, phenacetin, and resorcinol. Eutectic mixtures can have lower melting points than either pure component, making them useful in various applications such as pharmaceuticals and organic synthesis.
One way of determining if a sample of gold is pure, would be to compare the density with that of real gold.
