What is the maximum and RF value can be?
1, if it completely solube in the solvent, it will travel with it, right to the solvent front.
Where you could find the standard Rf values for fatty acids and poly unsaturated fatty acids?
Rf value of oleic acid with solvent system
What is the commercial value of kerosene?
- It is used as a jet fuel - It is used as a solvent in solvent extraction of metals, etc.
What are the TLC Rf values influencing factors?
Response Details:1) factor that affects the Rf value of TLC is the polarity of the solvent. If the solvent is too polar all of the compounds can run right up the plate resulting in poor separation.2) The RF value is used to established the identity of the spots of TLC plate.3) The RF value is ratio of the distance the solvent travels to the distance compound travels.4) The factors can affect RF values. The absorbent uniformity on the thin layer plate, same concentration(spotting is too weak or strong), room temperature during the mobile phase and development distance of the solvent during the mobile phase can all affect the results.5) Multiple solvent system are necessory when utilizing TLC for identification purposes.Response Details:1) factor that affects the Rf value of TLC is the polarity of the solvent.

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.
Why are Rf values always less than 1?
Rf values are distance of substance from origin divided by distance of solvent front from origin. As the substance travels with the solvent, the solvent will always have a greater or equal value to the distance travelled by substance. This means the highest value of Rf is 1.
What is the highest digit that can be written in a place value?
9 in the decimal system
Would RF values of amino acid you use in paper chromatography be the same if you use another solvent system?
Rf value is the ratio of distanced covered by solute by distanced covered by solvent.
What is the Rf value of salicylamide?
It will depend on the solvent system you are using.
What is the maximum and RF value can be?
1, if it completely solube in the solvent, it will travel with it, right to the solvent front.
What is rf value and how is determine?
the mobility of any component in a particular solvent is referred to as its RF value. Mathematically, RF value = distance travelled by solute/ distance travelled by the solvent
Where you could find the standard Rf values for fatty acids and poly unsaturated fatty acids?
Rf value of oleic acid with solvent system
What is the commercial value of kerosene?
- It is used as a jet fuel - It is used as a solvent in solvent extraction of metals, etc.
What is the highest place value of 397.9?
The highest place value is hundreds.
What is the highest place value in a decimal system?
The highest place value in the decimal system is the aleph null'th place. It should be noted that aleph null is an infinite number (in fact, it is the smallest infinity possible) and represents the cardinality of the natural number set. In other words, there is no finite number which is the highest place value in the decimal system. (The Aleph character breaks Answers.com's WYSIWYG editor. The Aleph null character looks like: 0א except that the 0 is on the other side of the aleph character )
How do you get the highest place value of a number?
what the answer the number 7,442 to the highest place value
What is the highest place value in 2704070321?
the highest place value is billions place.
