What is the filter paper with separate dyes called?
The filter paper with separate dyes is commonly referred to as chromatography paper. This paper is used in the process of paper chromatography, where different substances in a mixture are separated based on their movement and interaction with the paper and solvent. As the solvent travels up the paper, it carries the dyes with it, resulting in distinct, separated spots that can be analyzed.
Why do you use filter paper in chromatography?
Filter paper is used in chromatography to separate the components of a mixture based on their different rates of solubility and adsorption. The paper acts as the stationary phase, allowing the solvent to move the mixture components through it at different speeds. This separation allows for the visualization and characterization of individual components within the mixture.
What are some substances that can separated by a filter?
Sand, coffee grains and undissolved sugar all in water can be separated by a filter.
Can you differentiate colloids from solutions in terms of filter ability and stability?
Colloids cannot be separated by filtration due to their particle size being larger than in solutions. Solutions pass through filters easily due to their small particle size. Colloids are relatively stable over time compared to solutions, which may separate over time due to the solute settling at the bottom.
Name a piece of apparatus that can be used to drop the solvent on to the filter paper?
A Pasteur pipette or glass dropper can be used to drop the solvent onto the filter paper during the filtration process.
Why can't solutions be separated into the solute and the siolvent using filter paper?
Because the solute is soluble in the solvent.
How do you separate dye from black ink?
Dye and black ink can be separated by chromatography, where the mixture is dissolved in a solvent and allowed to move up a filter paper. The different components in the mixture will move at different rates based on their solubility in the solvent, allowing them to be separated visually.

Why cant a solute be separated by a solution by filtering?
Dissolve some sugar in water. Try and filter it out. Now, stir some bits of wood into water. Try and filter it out. You've just discovered the difference between a solution and a mixture.
Which type of mixture looks like a single substance and cannot be separated with filter paper?
Homogeneous mixtures, such as solutions, look like a single substance and cannot be separated using filter paper because the particles are evenly distributed at a molecular level. The components of a homogeneous mixture are not easily distinguishable, unlike in heterogeneous mixtures.
Why can you filter a suspension but not a solution?
You can filter a suspension because the particles are physically larger and can be trapped by the filter, whereas a solution has particles dissolved at the molecular level and passing through the filter. In a solution, the particles are homogeneously distributed in the solvent and cannot be separated by physical means like filtration.
Which passes through filter paper without being separated a suspension or a solution why?
A solution passes through filter paper without being separated, as it consists of uniformly mixed particles (solvent and solute) at a molecular level. In contrast, a suspension contains larger particles that do not dissolve and would be held back by the filter paper, leading to separation.
Why must the solvent front be near the top of the filter paper?
Having the solvent front near the top of the filter paper ensures that the separation process is efficient by allowing the components to be carried up the paper evenly. This helps prevent overlap of the separated components and ensures a clear resolution of the different compounds in the mixture.

How do you Separate sulfur powder?
One common method to separate sulfur powder is by using a process called filtration. This involves passing a mixture of sulfur powder and a solvent through a filter, with the sulfur powder remaining on the filter while the solvent passes through. The collected sulfur powder can then be dried to obtain the separated solid.
