When chalk (the mineral) dissolves in water, it's called "limewater".


Can napthaline powder dissolve easily in kerosene?

Yes, naphthalene powder dissolves readily in kerosene, as they are both nonpolar substances. Naphthalene is soluble in nonpolar solvents like kerosene due to similar intermolecular forces.


How is chalk destroyed?

Chalk is destroyed when it comes into contact with water or moisture, which dissolves the calcium carbonate that makes up the chalk. It can also be physically broken down by scraping or erasing, which breaks the chalk into smaller pieces or powder.


What beaverage dissolve chalk the fastest?

Chlorine bleach dissolves chalk the fastest because it is highly alkaline and breaks down the calcium carbonate in chalk quickly. However, it is important to note that this process can be hazardous and should be done with caution.


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.


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.


What solid dissolves best in water are twenty degrees Celsius salt sugar iodine chalk or urea?

Sucrose is the most soluble.


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.


How fast does chalk dissolve in water?

Chalk, which is primarily composed of calcium carbonate, dissolves very slowly in water due to its low solubility. The rate of dissolution can vary depending on factors such as temperature and agitation. In general, it can take several hours to several days for chalk to fully dissolve in water.


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.


Is ethanol soluble in kerosene?

ethanol (i.e ethyl alcohol) is a polar solvent. So ethanol is soluble in water. But Kerosene is non-polar solvent. Like dissolves like. This phenomenon is used here. Kerosene can dissolve non-polar solvents like naphthalene, which is a non-polar solvent.


Is it reversible when vinegar is spotted onto chalk or limestone?

When vinegar is spotted onto chalk or limestone, it creates a chemical reaction that dissolves the calcium carbonate in the rock. This reaction is not reversible as it breaks down the structure of the rock and changes it permanently.
