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.
What else can I help you with?
When crystal of copper sulphate strongly heated what residue obtain?
When a crystal of copper sulfate is strongly heated, it undergoes dehydration and turns into anhydrous copper sulfate, leaving a white residue. This white residue is the anhydrous form of copper sulfate, which has lost its water molecules during the heating process.
Why is it necessary to add anhydrous magnesium sulphate to the alcohol and ether during the sodium test?
Anhydrous magnesium sulfate is added to remove any traces of water from the alcohol and ether, ensuring a dry environment for the sodium test. Water can react with sodium and interfere with the test results, so removing it helps to ensure an accurate and reliable test.
Why is it necessary to weigh an anhydrous substance with a cover on?
Weighing an anhydrous substance with a cover on helps prevent moisture from the air from being absorbed by the substance, which could affect the accuracy of the measurement. By keeping the cover on during weighing, the substance is protected from exposure to moisture or other contaminants.
What is mean by isothermal in gas chromatography?
Isothermal in gas chromatography means that the temperature of the column is kept constant during the analysis. This helps to maintain consistent separation of the analytes as they pass through the column, allowing for accurate and reproducible results.
If a 2.743 g sample of magnesium sulphate crystals was heated strongly what would be the mass of the cooled dehydrated salt?
The mass of the cooled dehydrated salt would be less than 2.743 g because heating would remove water molecules, decreasing the overall mass. The exact mass would depend on the percentage of water lost during heating.
What are the properties of blue vitriol altered during water of crsytallization?
Blue vitriol is a very obsolete name for the copper(II)sulphate: CuSO4. Don't use in the future this term. Pentahydratated copper(II) sulphate: CuSO4.5H2O - bright blue color After the dehydratation of the above compound we obtain the anhydrous copper(II) sulphate: CuSO4 - pale green color.
When crystal of copper sulphate strongly heated what residue obtain?
When a crystal of copper sulfate is strongly heated, it undergoes dehydration and turns into anhydrous copper sulfate, leaving a white residue. This white residue is the anhydrous form of copper sulfate, which has lost its water molecules during the heating process.
What is the role of anhydrous sulfate?
Anhydrous sodium sulfate is considered as a drying agent. It is used in expirements to remove water from a solution or during an expirement. hope this helps.
Why is it necessary to add anhydrous magnesium sulphate to the alcohol and ether during the sodium test?
Anhydrous magnesium sulfate is added to remove any traces of water from the alcohol and ether, ensuring a dry environment for the sodium test. Water can react with sodium and interfere with the test results, so removing it helps to ensure an accurate and reliable test.
Does the mass increase or decrease when anhydrous compounds decompose?
when anhydrous compounds decompose their mass will decrease
Who discovered candy chromatography?
Candy chromatography was not discovered by one specific individual. It is a scientific technique that involves separating and identifying different components in candy dyes through a process similar to traditional chromatography.
Why is it necessary to weigh an anhydrous substance with a cover on?
Weighing an anhydrous substance with a cover on helps prevent moisture from the air from being absorbed by the substance, which could affect the accuracy of the measurement. By keeping the cover on during weighing, the substance is protected from exposure to moisture or other contaminants.
What is the Rf value of any insoluble dye?
Since insoluble dyes do not move with the solvent front during chromatography, they do not have an Rf value. Rf values are only calculated for substances that show movement during chromatography.
Why you use anhydrous ether during the preparation of Grignard's reagent why not anhydrous hexane?
You should really use anhydrous hexane; however, ethers can absorb large quantities of water; THF is completely miscible with water and will thus require extensive drying in order to get an anhydrous environment. Hexane absorbs very little water due to the unfavourable interactions between it and water. Therefore "non-anhydrous" hexane contains such a small quantity of water that the Grignard reagent formed will more than adequately dry the hexane.
Is dissolving anhydrous copper ii sulphate an exothermic reaction?
Oh, dude, you're asking about chemistry now? Well, technically, dissolving anhydrous copper II sulfate in water is an endothermic reaction because it absorbs heat from its surroundings. So, yeah, it's not exothermic, but hey, at least you're learning something, right?
What is chromatography fluid?
It refers to a set of technique used to separate different compounds. So involves separating chemicals and identifying them by color. Various chromatography products are used during the process.
What is mobile and stationary phase in Chromatography?
In chromatography, the mobile phase is the solvent that carries the sample through the stationary phase. The stationary phase is the material that interacts with the components of the sample, causing separation based on differences in their affinity for the stationary phase.
