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.

Is solubility a hydrogen bonding?
Based on the grammar of your question, you have no idea what solubility is. Solubility- the degree to which a substance can dissolve in a solvent(usually water). Hydrogen bonding is an intermolecular force of attraction that decreases relative solubility.
What is the ability of a substance to dissolve?
solubility
Solubility is the amount of substances dissolved in 100g of solvent?
Yes. The solvent can be in 100g.
How does increasing temperature affect the solubility of a gas solute?
Increasing the temperature of a solvent decreases the solubility of a gas Generally, increasing solvent temperature decreases the solubility of gases.
How is a solubility of a sunstance usually described?
The solubility of a substance is a measurement that describes how much solute dissolves in a given amount of solvent.
3 Why do the pigments become separated during the development of the chromatogram?
The chromatogram, or chromatography paper has solvent on it. Each pigment will separate itself from the others due to the relative solubility of that particular pigment.
Is solubility a hydrogen bonding?
Based on the grammar of your question, you have no idea what solubility is. Solubility- the degree to which a substance can dissolve in a solvent(usually water). Hydrogen bonding is an intermolecular force of attraction that decreases relative solubility.
What is the ability of a substance to dissolve?
solubility
What is the description of solubility?
Solubility is the ability of a solute to dissolve in a solvent in order to form a homogeneous solution. Relative solubility refers to the solubility of different substances.
How does increasing the temperature of a gas solvent affect the solubility of a gas?
Increasing the temperature of a solvent decreases the solubility of a gas Generally, increasing solvent temperature decreases the solubility of gases.
Is solubility a characteristic of matter?
Solubility is a characteristic of the solvent.
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 two factors determine the rate at which the pigments travel up the chromatography paper?
Rf value. polarity of solvent
The ability of a substance to dissolve in a solvent is called?
The ability of a solute to dissolve in a solvent at a certain temperature is called solubility. The solubility of most solids in water increases with temperature increases.
How can solubility increase?
1) Strong solute-solvent greater solubility while weak solute-solvent attractions equate to lesser solubility 2) Temperature (for gaz high temperature decrease solubility) 3) Pressure for solubility gaz in liquid 4) Polarity of solvent: Like dissolves like
Solubility is the amount of substances dissolved in 100g of solvent?
Yes. The solvent can be in 100g.
How does increasing temperature affect the solubility of a gas solute?
Increasing the temperature of a solvent decreases the solubility of a gas Generally, increasing solvent temperature decreases the solubility of gases.
