When chalk (the mineral) dissolves in water, it's called "limewater".
All the products which dissolve in water completely are soluble products like sugar, salt etc while the products which didn't dissolve in water completely are non soluble products like sand, chalk dust etc.
Substances which can be dissolved in a solvent are said to be soluble in that solvent.For ExampleSugarSaltbaking powderwashing sodathese are in soluble in water.

No, it is a physical, not chemical change.
Most people think of something being soluble if it will dissolve in water. Sawdust doesn't dissolve in water. In general the cellulose and other structures that compose sawdust are not particularly soluble until they are broken down chemically - which is not really dissolving. Once they have been broken down, the resulting products can be dissolved - but at that point you aren't really dissolving sawdust anymore, you are dissolving the products of the chemical reactions that have broken down the sawdust.
No it is not soluble things that sre soluble are things that can dissolve in water. for example salt, sugar and chalk dust are all soluble :) ohh and things that do dont dissolve in water is called insoluble an example of an insoluble things are solid,copper wire and lots more :)) thanks:)))))))))))))))))))))))))))))
First remove iron filings with a magnet. That leaves sand, salt and chalk dust. Add water which dissolves the salt, and filter leaving the sand and chalk dust on the filter paper. Put that back in water and add acid to dissolve the chalk dust (CaCO3) leaving the sand as a solid. Filter to obtain the sand. The chalk dust will now be in the acid as CO2 and H2O and the Ca salt of the acid.
we can filter the mixture of table salt and chalk dust by using the process called filtration because when you mix the table salt with water and chalk dust together, it becomes an insoluble mixture called suspension
All the products which dissolve in water completely are soluble products like sugar, salt etc while the products which didn't dissolve in water completely are non soluble products like sand, chalk dust etc.
Chalk is a form of calcium carbonate, so chalk dust is also a form of calcium carbonate.
it is a suspension because; suspension = a solid and a liquid mixing which is what chalk dust and water is. :)
My sister got chalk dust in her eyes and i told her how to get it out. This is what I told her, blink really fast and you should get tears to come out of your eyes. Also, you can splash cold water on your eyes.
Maybe :3
A scientific name for Chalk is called "Calcium Carbonate".
crushed limestone then it is pressurized so that it for like a solid rock but is not as rigid as a rock because you can write with it on a blackboard.
The chalk will be ground into chalk dust by the pebbles.
dust from a chalk. Chalk is made from calcium carbonate, CaCO3.
