What are two substances that do not leave the glomerulus during filtration?
Substances like blood cells and large proteins do not normally leave the glomerulus during filtration in the kidneys. These large molecules are retained in the blood as they are too big to pass through the filtration barrier.
What is a collecting bottle and how is it used?
A collecting bottle is a container used for collecting liquid or gas samples during an experiment or testing process. The bottle is typically connected to a sampling device, such as a pipette or pump, which allows the precise transfer of the sample into the bottle without contamination. Once the sample is collected, the bottle can be sealed to preserve the sample for further analysis.
Why does substance remain in the funnel during filtration?
Substance may remain in the funnel during filtration due to clogging of the filter paper by fine particles, improper wetting of the filter paper before filtration, or insufficient pressure to facilitate the filtration process. Additionally, some substances may have a tendency to stick to the filter paper or be insoluble in the solvent being used for filtration, leading to retention in the funnel.
What is the use of beaker cover?
A beaker cover is used to prevent contamination of the contents inside the beaker during storage or when the beaker is not in use. It helps to keep the contents clean and free from dust, debris, or other contaminants. Additionally, it can also help prevent accidental spills or evaporation of volatile substances.
what instrument used to support the beaker ,flaskor other glass ware during heating?
tripod
Why must the stem of the funnel touches the inside surface of the collecting beaker during the filtration?
it's done to minimize the mixing of air into the filtered solution. By touching the stem to the collecting beaker, the solution flows into the beaker smoothly rather than splashing into it.
What is used to hold filter paper?
A filter paper is typically held in a funnel during filtration. The funnel is often placed in a ring stand or held by a clamp to support it during the filtration process.
What does the wire gauze do when heating a beaker with a Bunsen burner?
The wire gauze spreads the heat evenly from the Bunsen burner to the beaker, reducing the risk of hot spots and breakage. It also provides a stable surface for the beaker to rest on during heating.
Why do fish tank filters have charcoal in?
The charcoal in some filters actually perform chemical filtration in your fish tank filter. The porous surface of the charcoal traps minutes traces of nitrates and phosphates during the filtration process.
Why do you need to flute your filter paper in filtration?
Fluting filter paper during filtration enhances its surface area and increases the speed of filtration. The fluted design allows for better flow of liquids by reducing the resistance to the passage of the filtrate, preventing clogging and improving the efficiency of the process. Additionally, it helps create more space for the solids to settle, resulting in clearer filtrate.
What is the color of the Beaker?
The color of a beaker can vary, but most commonly they are made of glass and have a transparent or slightly tinted appearance. This allows for easy visibility of the contents inside the beaker during experiments and measurements.
Why crystals disappear during suction filtration of a sample crystallized from benzene?
Crystals may disappear during suction filtration of a sample crystallized from benzene if the crystals dissolve in the solvent being used for filtration, or if they break up into smaller particles that pass through the filter. This can happen if the crystals are not fully dried or if too much force is applied during filtration.
Why the beaker covered during the development of chromatogram?
During the development of a chromatogram, it is better to cover it with a beaker to prevent evaporation, which will affect the movement of the solute and solvent system. This will ensure that the chromatogram will develop properly.
What is calibration of beaker?
Calibration of a beaker involves verifying its volume capacity by comparing measurements with a standard reference. This is important to ensure accurate and reliable measurements during experiments and to account for any discrepancies in the beaker's dimensions. Calibration is typically done by filling the beaker with a known volume of liquid and confirming the measurement markings on the beaker.
Why is a cover the beaker in TLC experiment?
Covering the beaker during a TLC experiment helps to prevent evaporation of the solvent, which could lead to changes in the concentration of the compounds being analyzed. Additionally, it helps to maintain a stable environment inside the beaker, ensuring consistent results during the experiment.
When was the beaker invented?
The beaker was invented around the 16th century. It is believed to have been developed in Europe, likely by alchemists or chemists during the Renaissance period. The exact date and inventor of the beaker are unknown.
What is a collecting bottle?
In a chemical laboratory collecting bottles are used to collect a gas released during an experiment.
