Why adding sand and MgSO4 in analyte during chromatography?
Adding sand can help to improve the separation of components by reducing column packing heterogeneity and promoting more uniform flow of solvent. Magnesium sulfate (MgSO4) can be added to remove water from the sample, which can improve the chromatographic separation and prevent water-induced peak distortion.
Why add sand and anhydrous magnessium sulphate to a leaf during chromatography?
Adding sand and anhydrous magnesium sulfate to a leaf during chromatography helps to break down the plant cells and extract the pigments effectively. Sand mechanically grinds the leaf tissue, while anhydrous magnesium sulfate acts as a drying agent to remove water from the leaf, allowing for better separation of pigments during chromatography.
Is sand and water evaporation or distillation or filtering or chromatography?
FilteringThe sand will be caught by the filter paper as residue and the water will come out the bottom of the filter funnel as the filtrate.
Is sand added to water a mixture or pure substance?
Sand added to water is a mixture. Sand is a solid substance composed of tiny particles, while water is a liquid. When sand is added to water, it does not undergo a chemical change and can be separated back into its original components.
Why is limestone added to the blast furnace during the extraction of iron?
Limestone is added to the blast furnace during the extraction of iron to act as a flux. It helps to remove impurities, such as silica, from the iron ore by combining with them to form slag. The slag can then be easily separated from the molten iron.

Why is sand added during chromatography of leafs?
Sand is added during chromatography of leaves to provide a stable support for the plant material and to aid in the extraction process. It helps to separate the pigments more effectively by creating a porous medium through which the solvent can move, allowing for better diffusion and separation of the different pigments present in the leaf. Additionally, sand can help to prevent the plant material from clumping together, ensuring a more uniform distribution during the chromatography process.

Sand mechanically grinds the leaf tissue, while anhydrous magnesium sulfate acts as a drying agent to remove water from the leaf, allowing for better separation of pigments during chromatography.
Why do we add sand and magnesium sulphate in chromatography?
In chromatography, sand is often added to the stationary phase to provide a solid support that enhances the separation process by increasing the surface area for interactions with the mobile phase. Magnesium sulfate acts as a drying agent to remove moisture from samples and can help stabilize certain compounds during the separation. Together, they improve the efficiency and resolution of the chromatographic separation.
Can you use chromatography to separate sand from water?
No, chromatography is not suitable for separating sand from water. Chromatography is a technique designed for separating and analyzing mixtures of substances, typically in liquid or gas phases, based on their differing affinities for a stationary phase. Since sand is a solid and does not dissolve in water, a more appropriate method for separation would be filtration, where the sand can be trapped by a filter while allowing the water to pass through.
Is sand and water evaporation or distillation or filtering or chromatography?
FilteringThe sand will be caught by the filter paper as residue and the water will come out the bottom of the filter funnel as the filtrate.
Consider a mixture of water sand and oil.how many pahese are present?
You can separate them using chromatography.
Is sand added to water a mixture or pure substance?

What is faster sand or water?
During movement water is faster than sand and during cooling sand is faster than water.
What if salt was added in with sand and iron fillings?
maybe it will melt
What is the term called when separating sand from water?
ways of separating liquids, simple distillation, fractional distillation, paper chromatography, thin layer chromatography, filtration, evaporation, crystallisation, separating funnel, decantation, centrifuge, centrifuging, decanting-decantation, instrumental methods of analysis, glc gas-liquid chromatography, purifying substances
Can new live sand be added to exsiting live sand in saltwater aquarium?
Yes, but be prepared for some cloudy water.
