if it wouldn't be above the level of solvent the spots will run off

If the solvent level reaches the pencil line where the spots are, it can dissolve the compounds in the mixture, causing them to spread out and overlap. This can lead to inaccurate results and difficulties in analyzing the separated components on the chromatogram. It's important to maintain the separation of the compounds on the chromatography plate for clear identification.

Why must the level of the solvent not reach the pencil line where the spots are?
Allowing the solvent to reach the pencil line could oversaturate the spot, leading to uneven separation and inaccurate results. It may cause the compounds in the spot to spread out too much or merge with neighboring spots, making it difficult to accurately identify and analyze the components.
When a solvent is holding the maximum amount of solute for that given temperature?
A saturated solution
How do you reach crystallisation point?
To reach crystallization point, a solution is cooled slowly to allow the solute particles to come together and form a crystalline solid. The temperature at which crystallization occurs will depend on the specific solute and solvent being used.
Does water dissolve and transport substances?
Yes, water is known as the "universal solvent" because it has the ability to dissolve a wide range of substances. Water can transport dissolved substances within the body or through the environment, making it essential for many biological and chemical processes.
What is the tendency of a solute to change the boiling of a soild called?
The tendency of a solute to change the boiling point of a solvent is called boiling-point elevation. This occurs because the presence of the solute disrupts the solvent's ability to form vapor, therefore requiring more heat to reach the boiling point.

How do you complete chapter 5 level 5 on save the pencil?
To complete Chapter 5 Level 5 in Save the Pencil, you need to carefully navigate the pencil through the obstacles on the track to reach the finish line. Use the eraser to remove obstacles or create a path for the pencil to follow. Timing and precision are key to success in this level.
How do you take a pencil out of a pencil case?
Simply unzip the pencil case, reach in, and carefully grab the pencil to pull it out. Be sure to watch out for any sharp edges or other items in the case while removing the pencil.

What is the greatest amount of solute that a solvent can dissolve?
A solvent will only dissolve enough solute to reach its saturation point. Exact quantities are defined by the nature of the specific solvent ant solute, and the prevailing environmental conditions.

If a stone and a pencil are dropped simultaneously in vacuum fron the same height which of two will reach the ground first?
In vacuum, both the stone and the pencil would fall at the same rate due to gravity and there would be no air resistance to affect their acceleration. Therefore, both the stone and the pencil would reach the ground at the same time.
What happens to solute molecules when the solvent evaporates or boils?
When the solvent evaporates or boils, the solute molecules become more concentrated as the solvent decreases. Eventually, the solute may reach a point where it precipitates out of the remaining solvent as a solid.
What is the maximum amount of solute that can be dissolved in a solute at a particular temperature?
This is known as the solubility of the solute in the solvent. When you reach the maximum it is know as the saturation concentration. Adding any more solute will not dissolve in the solvent.
