How is crystallization better than evaporation?
Crystallization is better than evaporation in mainly two ways, : 1. in evaporation, the solution needs to be at the boiling point of the solvent, the whole time. This may degrade the solute. 2. in crystallization, the crystals automatically throw away impurities to arrange themselves in a regular manner. Therefore, the degree of purity is higher than the solute left after evaporation.
Would a longer fractioning column be more efficient in separating mixtures than a shorter one?
Yes, a longer fractioning column would generally be more efficient in separating mixtures than a shorter one. This is because a longer column allows for more separation stages and more interaction between the components of the mixture, resulting in better separation.
Why are mixtures to be separated by chromatography heated first before separated?
Heating the mixture in chromatography helps to increase the solubility of the components in the mobile phase, making them more likely to interact with the stationary phase and separate properly. Additionally, heating can reduce the viscosity of the mobile phase, allowing for better flow rates and improved separation efficiency.
How is crystallization technique better than simple evaporation technique to get a pure solid?
Crystallisation is the most common method to purify soluble solids. It is preferred over evaporation to dryness as many substances decompose upon strong heating. Also, when all the water is removed during evaporation, any soluble impurities will be left on the crystals (eg. sugar decomposes to become carbon when it is heated strongly). The shape and size of crystals can be controlled by controlling variables such as cooling rate and evaporation rate.In crystallisation, water is removed by heating the solution. Heating stops when a hot saturated* solution is formed. The resulting solution is left to cool and the dissolved solid will then be formed as pure crystals. This is because the solubility of the solute decreases as the temperature drops. At a lower temperature, less solute can be dissolved in the solution.
What is the function of glass beads in a fractionating column?
Glass beads in a fractionating column provide a larger surface area for vapor-liquid contact, promoting better separation of components based on their boiling points. They help increase the efficiency of the distillation process by providing more contact points for condensation and re-evaporation of vapors.

Is crystallisation better than evaporation?
It depends on the specific goal. Crystallization is often preferred when purity is important, as it allows for the separation of a pure solid compound from a solution. Evaporation is more commonly used for concentrating solutions or recovering dissolved solids. Ultimately, the choice between crystallization and evaporation will depend on the desired outcome of the process.

Why urine and feces mixtures is better fertilizer?
because you can drink it ;)
Can you give a sentence using the word with separation?
Filtering, is one of many separation techniques.
Which one is better maximum carnage or separation anxiety?
i think maximum carnage is better write what you think.
Does evaporation work better than coffee filters?
That would depend on what you are doing.
Can we combine more than one separation techniques to get better results?
yes

Why is it good to use alcohol when doing chromotography?
Alcohol is commonly used in chromatography as a solvent because it has a low boiling point, which helps with the evaporation process. It also has good solvating power, allowing it to dissolve a wide range of compounds. Additionally, alcohol can help achieve better separation of different compounds due to its varying polarity.
