When chalk dust dissolve in water it is called?
When chalk dust dissolves in water, it forms a suspension called "chalk slurry." This mixture consists of tiny chalk particles dispersed in water.
Does Chalk Dissolve in Lemon Juice Vinegar or Water first?
Chalk dissolves first in vinegar, followed by lemon juice, and lastly in water. This is because vinegar is acidic and reacts with the calcium carbonate in chalk to form a soluble calcium salt. Lemon juice, also acidic but less so than vinegar, dissolves chalk at a slower rate. Water alone does not chemically interact with chalk to dissolve it.
Is ethanol soluble in kerosene?
No, ethanol is not soluble in kerosene because they are both nonpolar substances. Ethanol is a polar molecule, while kerosene is a nonpolar hydrocarbon. As a result, they do not mix together and remain separate phases.
What happen when dilute nitric acid is added to a sample of chalk?
When dilute nitric acid is added to a sample of chalk (calcium carbonate), it reacts to form calcium nitrate, water, and carbon dioxide gas. This reaction is a chemical change that results in effervescence due to the release of the carbon dioxide gas. The chalk dissolves as it reacts with the nitric acid.
Why kerosene oil is not dissolved in water?
Kerosene oil is a nonpolar molecule, while water is a polar molecule. Because they have different polarities, they do not mix well together. This is due to the principle that "like dissolves like" - nonpolar substances tend to dissolve in nonpolar solvents, and polar substances tend to dissolve in polar solvents.
Why do you use marble and not chalk to make floors?
Marble is a harder and more durable material compared to chalk, making it better suited for flooring in terms of longevity and resistance to wear and tear. Marble also offers a luxurious and elegant aesthetic that is preferred for high-end applications like flooring in homes, hotels, and other commercial buildings. Additionally, marble can be polished to a high shine and comes in a wide range of colors and patterns, providing more design options compared to chalk.

Why is powdered chalk more like a liquid than a lump of chalk is?
because it consists of small particles that are similar to liquid. Even if we add water to a powdered chalk, it dissolves easily whereas a lump of chalk is harder to dissolve in water.
Why does cola dissolve chalk?
Chalk is calcium carbonate. Cola is an acid. When these two compounds mixed, hydrogen carbonate is formed. This compound is water soluble, and thus chalk mixed with and acid like cola dissolves in water.
When chalk dissolves in water how can it be collected?
Chalk particles can be collected by using a filtration process. A filter paper or a fine sieve can be used to separate the dissolved chalk particles from the water. The water can then be evaporated to obtain the solid chalk residue.
Is ethanol soluble in kerosene?
No, ethanol is not soluble in kerosene because they are both nonpolar substances. Ethanol is a polar molecule, while kerosene is a nonpolar hydrocarbon. As a result, they do not mix together and remain separate phases.
What solid dissolves best in water are twenty degrees Celsius salt sugar iodine chalk or urea?
Sucrose is the most soluble.
What soda dissolves chalk fastest?
None. It will depend on the initial temperature of the soda, not the brand.
Why is it that sodium chloride is insoluble in kerosene?
When sodium chloride dissolves in water it does so because the positive and negative ions are attracted to the polar water molecules. Benzene molecules are not polar so there is much less attraction.
Will salt dissolve faster in vinegar or salt?
Depends on the pH of the water but it would dissolve faster in fresh water because there isn't as much stuff in solution. true... but it took me about 8.30 seconds to dissolve with the perfect pH.....
Why do mothball powder and margarene dissolve in kerosene but not in the water?
Mothball powder and margarine are non-polar substances, while water is a polar solvent. Since like dissolves like, non-polar substances like mothball powder and margarine dissolve in non-polar solvents like kerosene, but not in polar solvents like water. This is due to differences in the molecular structures and interactions between the substances.
What is happening in the ocean?
Increased carbon dioxide in the atmosphere can become dissolved in the ocean forming an acid called carbonic acid. This acid results from carbon dioxide combining with water and this also contributes to the acidity of soda. The increased acidity of the ocean makes it more difficult for animals and corals to form shells which are made of calcium carbonate, the same material as chalk since calcium carbonate dissolves in acid. As a experiment, try adding lemon juice to a little piece of chalk or chalk powder. You can see how the acid from the lemon juice dissolves the chalk and bubbles from this. These bubbles are carbon dioxide and that the chalk or chalk powder disappears. This reaction happens to a much slower extent to seashells or the shells that corals try to form making more difficult for corals and certain other sea creatures.
