What is the solubility of 2-mercaptobenzimidazole?
2-mercaptobenzimidazole has limited solubility in water, but it is more soluble in organic solvents such as ethanol, methanol, and acetone. Its solubility can vary depending on the specific conditions such as temperature and pH.
Would you expect RF number of a pigment to change if we altered the composition of the solvent why or why not?
No, the solubility of the pigment molecule in its organic solvent is a factor involved in the separation of pigments. More soluble molecules move faster and generally travel further. Chlorophyll B is a great example since its only soluble in fat solutions.
What are the effects of dissolving?
Dissolving involves breaking down a substance into smaller particles due to interactions with the solvent. This process usually results in the formation of a homogeneous mixture with the solvent. The dissolved substance's properties, such as taste, color, and solubility, can change, but its chemical composition remains the same.
Does salt or ink dissolve at the same rate at different temperatures?
Salt will generally dissolve faster in warmer water due to the increased kinetic energy of the water molecules. In contrast, the rate of ink dissolution may not be as affected by temperature since its solubility is primarily determined by other factors such as the solvent used and the chemical composition of the ink.
Is solubility a quantitative property?
Solubility is the property of a liquid, solid, or gaseous chemical matter known as a solute to dissolve in a solid, liquid, or gaseous solvent. Solubility is also frequently said to be one of the distinctive properties of a substance. (: good luck!
What are the properties of an ideal recrystallization solvent?
An ideal recrystallization solvent should have high solubility for the compound at high temperatures to dissolve the impurities and low solubility at low temperatures to allow the compound to crystallize out. It should also be chemically inert towards the compound, easily evaporated to recover the purified compound, and have a boiling point lower than the melting point of the compound.
What is the difference between saturation and solubility?
Saturation and solubility is the same. They both meant to point out the maximum of solute dissolved through out the solvent.
How is solubility related to temperature?
This relationship is most often observed when dealing with liquid solutions. The solubility of solids and liquids in a liquid solvent tends to improve as the solvent's temperature increases, while the solubility of gases in the same type of solvent generally decreases as its temperature rises.
How do you compare solubility between substances?
Solubility can be written as %m/m (mass in g per 100g), %m/v (mass in g per 100mL), %v/v (mL per 100mL), ppm (parts per million), ppb (parts per billion) etc. Solubility is also dependant on pressure and temperature. Due to these variables, in the same units (eg. %m/m) and at the same set of temperature and pressure (SLC or STP) you can compare the solubility values.
Is solubility a physical or chemical propety?
Solubility is a physical property because it is related to a physical, not a chemical, change. When something dissolves, it does not change chemically. It is still the same compound/molecule, etc. when it was not dissolved in the solvent.
Is solubilty the same as a chemical Change?
Solubility is forming of chemical bonds between solute molecules and solvent molecules, hence a chemical reaction.
Would you expect the Rf value of a pigment to be the same if a different solvent were used Explain?
The Rf value would not be the same for every solvent as there are factors that allow each solvent to be unique. The attractive force, particle size and solubility of each solvent will create different results each time.
What do the Rf values indicate about the relative solubility of the pigment in the the solvent?
The Rf values do not indicate the solubility of a substance. The Rf value or retardation factor is the ratio of the distance traveled by the center of a pot to the distance traveled by the solvent front in chromatography.
Are all solids equally soluble in the same solvent?
Absolutely not! Using gasoline as a solvent, wax dissolves in it but glass will not dissolve at all. Using water as a solvent, salt dissolves in it but pepper will not dissolve at all. Using hydrofluoric acid as a solvent, glass dissolves in it but wax will not dissolve at all.
