because when we usually test for a liquid or anything soluble we put a drop of it on the pencil line, then when we put the chromatography paper or filter paper in water the water will get on the paper and start moving upwards here when the water will approach the liquid or solvent or die and then they will move with water throughout the filter or chromatography paper.
What else can I help you with?
Is a pencil dencer then water?
no, a pencil will float therefore it is less dense than water(ticonderoga #2 pencil was used)no pencils were harmed in the execution of this experiment
What is a sentence for the word ripple?
Dropping a pencil in the water will produce ripples.
How do you separate the colours in biro ink?
Chromatography cannot be used because biro ink does not dissolve in water. I actually dont know how to separate the colors in Biro ink.. :( sorry, but look it up on google.com!
Why is there standing water in your dishwasher what is wrong?
water remains in dish washer after completion of cycle, WHY?
Hot can you make a compass?
There are a few different kinds of compass. To make a compass that makes circles you could use a pencil and tie it to another pencil and trace circles.
How can you separate a single color from ink?
a process called chromatography. you put some ink on spetial paper on a line dip it in water just below the line. the ink should then seperate.
Why is it important to use only a pencil to mark the starting line of the chromatogram?
This is so you can know the base line. The base line is used as the starting point for the mesaurements used for the Rf values. you need to know the distance from the base line to the point of the spot to know the Rf values. see related link below for more info about paper chromatography
Why does a pencil immersed in water appear to be displaced at the interface of air and water?
Take a pencil and a glass of water, and put the pencil in it. The apparent displacement of a pencil in the water is due to refraction, which is the change of direction of a wave as it moves from one medium into another.Light is being reflected off the pencil to allow us to see it. The light reflected off the part above water is propagated through air to our eyes. The part below the water must move through the water and then through the air for us to see it. As the light moves from the water into the air, it undergoes refraction, and changes direction. The part of the pencil below the water appears displaced to the viewer.
What solvent can be used for food colorings when doing paper chromatography?
Water should work well as food colourings are usually water soluble.
What makes a pencil bend when put in water?
When a pencil is put in water, the water molecules are attracted to the pencil's surface due to adhesion. This attraction causes the water molecules to bond with the pencil molecules, changing the pencil's structure and making it appear bent when viewed through the water.
What are two industries that use chromatography?
Two industries that use chromatography are pharmaceuticals and environmental testing. In pharmaceuticals, chromatography is used for drug development and quality control. In environmental testing, chromatography helps analyze pollutants in air, water, and soil.
Why water peak not coming in gas chromatography?
Water peaks do not typically appear in gas chromatography because the mobile phase used is a gas (rather than a liquid) that does not interact with water molecules in the same way. Water peaks are common in liquid chromatography due to the presence of a liquid mobile phase.
Will water extract pigment in a chromatography?
Yes, water can extract pigment during chromatography. This technique uses a solvent to separate and analyze mixtures, and water is often used as the solvent for certain types of pigments. Water's polarity can help separate different pigments based on their solubility and interactions with the paper or gel used in chromatography.
What is the best solvent for phenol for use in Gas Chromatography?
water
Does a pencil remain the same when it is dipped in a glass of water?
No, the pencil will appear larger and distorted when it is dipped in a glass of water due to refraction of light. The change in appearance is caused by the bending of light as it passes from air to water, making the pencil look bent or broken.
How do you do chromatography?
I f you want to observe this theory in simple way ,you can observe it through using filter paper has ink on it and leave it in water ,after time when the water get evaporated you will observe that the ink was separated and this is a simple chromatography. And this is core concept for chromatography. Saleh Qahtani Lab Tech
Why when a pencil is in water it looks like if it's broken?
When a pencil is placed in water, light passing from air to water through the water's surface is refracted due to the change in speed. This refraction causes the light rays from the pencil to bend at different angles, making the pencil appear broken at the water's surface.
