Why was it necessary to avoid solvent from splashing to the side of beaker?
It is necessary to avoid solvents from splashing onto the sides of a beaker to prevent contamination of the solvent and potential loss of material. Splashing can also lead to inaccurate measurements, affecting experimental results. Additionally, solvents may be hazardous; preventing splashes minimizes the risk of spills and exposure to harmful chemicals.
When dissolve water in a beaker water is the?
Water is the solvent.
Why is it necessary to keep the beaker used for chromatography tightly covered with para film while the solvent is rising through the TLC slide?
Keeping the beaker covered with Parafilm helps prevent the solvent from evaporating too quickly, which could lead to uneven solvent front movement on the TLC slide. This ensures a consistent and accurate separation of compounds on the TLC plate.
Why must the stem of the funnel touch the inside surface of the collecting beaker during filtration?
Ensuring the stem of the funnel touches the inside surface of the collecting beaker helps to prevent splashing or spillage of the liquid being filtered. It also helps to direct the filtered liquid smoothly into the beaker, minimizing the risk of contamination or loss of sample during the filtration process.
Why is it important that the sample spots are not below the solvent level when the filter paper is first placed in the developing chamber?
By placing the spot above the level of the solvent in the beaker, you slow the flow of solvent which results in improved separation of the components in the spot. If you placed it below the level of the solvent in the beaker, the solvent would just flow at a much faster rate and instead of separating the components in the spot, they would simply be washed away.

Why is it important to place the developing solvent in a clean dry beaker?
Placing the developing solvent in a clean, dry beaker helps prevent contamination or interference with the chromatography process. Any residues or impurities in the beaker could affect the separation of the compounds being analyzed, leading to inaccurate results. A clean, dry beaker ensures the purity of the solvent and the reliability of the chromatography experiment.

It also helps to direct the filtered liquid smoothly into the beaker, minimizing the risk of contamination or loss of sample during the filtration process.
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.
Make a sentence with the word solvent?
When you dissolve salt into water, the salt is the solute while the water is the solvent.
How do you find the mass of a solvent?
In order to determine the mass of a solute, there are a few things you need to know. I am assuming you already know the compounds, and you know about molar mass. If you know the mass or number of moles or possibly volume of solution, and the molarity or mass percent, you can calculate the mass of solute.
Why is it important that the sample spots are not below the solvent level when the filter paper is first placed in the developing chamber?
By placing the spot above the level of the solvent in the beaker, you slow the flow of solvent which results in improved separation of the components in the spot. If you placed it below the level of the solvent in the beaker, the solvent would just flow at a much faster rate and instead of separating the components in the spot, they would simply be washed away.
How do you measure weight and volume of water not quite filling a 50ml beaker?
It is necessary to know the mass of the empty beaker.
What is a sentence with the word solvent?
Solvent - the chemical that dissolves, or a state of stable financial liquidity (Noun) "Only a certain amount of a solid can be absorbed in a solvent." (Adjective) "The bank was determined to keep the company solvent."
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.
