The rm value (also known as retention factor) in chromatography is a measure of how strongly a compound is retained by the stationary phase relative to the mobile phase. It is calculated as the distance traveled by the compound divided by the distance traveled by the solvent front. The rm value helps in characterizing and identifying compounds based on their behavior in the chromatographic system.

What is the Rf value of 4-aminophenol?
The Rf value of 4-aminophenol depends on the specific chromatography conditions used. It is typically around 0.6-0.7 in most common chromatography systems.
What is Rf value?
Rf value, or retention factor, is a measure used in chromatography to quantify the separation of components in a mixture. It is calculated by measuring the distance a compound travels up the chromatography plate relative to the distance the solvent front travels. Rf value is specific to the solvent system and chromatography conditions used.
What is the Rf value of any insoluble dye?
Since insoluble dyes do not move with the solvent front during chromatography, they do not have an Rf value. Rf values are only calculated for substances that show movement during chromatography.
What is the rf value of xanthaphyll?
The Rf value of xanthophyll can vary depending on the specific conditions of a given chromatography experiment. However, in general, the Rf value of xanthophyll is typically around 0.6 to 0.7 when using silica gel chromatography with acetone and hexane as the mobile phase.
What are the different types of chromatography?
there are different types like gas chrom. and thinlayer chrom Answer: There are two types of chromatography:liquid chromatography gas chromatography

Rf value is specific to the solvent system and chromatography conditions used.
What is the relationship between polarity and RF value in chromatography?
In chromatography, the relationship between polarity and RF value is that compounds with higher polarity tend to have lower RF values. This means that polar compounds will move more slowly through the chromatography system compared to non-polar compounds.
What is an rf value used for?
The rf value is shorthand for the retention value of a substance. It is used in chromatography to determine the components of an unknown sample.
What is the Rf value of any insoluble dye?
Since insoluble dyes do not move with the solvent front during chromatography, they do not have an Rf value. Rf values are only calculated for substances that show movement during chromatography.

How long does it take a principal of RM 25000 at a simple interest rate of 5 percent to become RM 30000?
4 time periods (eg 4 years if the 5% simple interest were added each year). In simple interest, the interest is added, but attracts no interest itself (that is compound interest) - only the original value attracts the interest: 5% of RM 25000 = RM 1250 added each time RM 30000 - RM 25000 = RM 5000 RM 5000 ÷ RM 1250 = 4 time periods

What are 3 types of chromatography?
1. thin -layer chromatography 2. gas chromatography 3. liquid chromatography
What is substance that have 0.803 Rf value?
The Rf value of a substance is a measure of its migration distance during chromatography. A substance with an Rf value of 0.803 would mean that it traveled 80.3% of the total distance from the origin to the solvent front during the chromatography process. The specific identity of the substance would depend on the experimental conditions and the properties of the compound.
