Factors that affect leaf chromatography include the polarity of the solvent used, the size and shape of the molecules being separated, the pH of the solvent, and the temperature at which the chromatography is performed. These factors can impact the rate at which the molecules move through the chromatography medium and the resolution of the separation.
Chromatography is the laboratory technique used to separate the different pigments in a green leaf. The leaf pigments are separated based on their solubility in the solvent used. By analyzing the bands of separated pigments, researchers can identify and quantify the different pigments present in a leaf.
This solvent is used to clean surfaces from polyester resins.
When a leaf is boiled in alcohol, the alcohol acts as a solvent, extracting chlorophyll and other pigments, which can weaken the leaf's cell structure. The heat from boiling also denatures proteins and other cellular components, causing the cell walls to lose their integrity. As a result, the leaf becomes brittle and more fragile, losing its flexibility and resilience. This process is often used in preparation for microscopy to make the leaf more transparent and easier to study.
There is no answer to this question. "Extract" is, well, extracted from the leaves using a solvent, and since leaves vary in size and essential oil content, and extracts vary in the relative proportions of essential oil to solvent, there's no possible way to give a single answer.

Decolourise
Carotene travels the farthest in chromatography of leaf pigments because it is the least soluble in the chromatography solvent. This means it interacts less with the solvent and more with the chromatography paper, allowing it to move further up the paper before the solvent front stops it.
When a leaf is placed in alcohol, the alcohol acts as a solvent and removes the chlorophyll from the leaf, causing it to lose its green color. Other pigments present in the leaf may remain, giving the leaf a different color appearance.
Ethanol is an alcohol that can be used as a solvent.
This solvent is used to clean surfaces from polyester resins.
The purple KMnO4 is decolourise
Water (H2O) is largely used as a solvent; but an universal solvent cannot exist.
It is a solvent.
Eco solvent.
We used acetone as a solvent to dissolve the paint from the surface.
