It turns blue. Since chalk ( CaCo3) is a base and when pink litmus paper reacts with a base it turns blue
it is a suspension because; suspension = a solid and a liquid mixing which is what chalk dust and water is. :)
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.
Nothing will happen when you add water to chalk, because chalk does not dissolve in water. However, if you are drawing with chalk, as the water evaporates, it will allow the chalk to spread and create more fun.
chalk is a compound
Chalk is a sedimentary rock composed of the skeletal remains of tiny marine organisms and is composed mainly of the mineral calcite. As such, chalk is not a mineral.
Add chalk (Calcium carbonate) if it is an acid the chalk will 'fizz' as it reacts and it will give off carbon dioxide gas. Or just use a universal indicator solution or test with litmus paper.
chalk has a compound in it that releases the glow when wet.
Bubbles are formed when chalk is dipped in water due to the release of carbon dioxide gas. Chalk is made of calcium carbonate, which reacts with the water to produce carbon dioxide gas bubbles. This reaction is known as effervescence.
yes you can
the natural state of 'chalk' is green when they make it It's true , because I'm a person who studies chalk
the colour of chalk(calcium carbonate) in its natural state is white.
To separate chalk from a mixture of chalk and copper sulfate solution, you can add water to dissolve the copper sulfate, leaving behind the chalk. The water-soluble copper sulfate will form a blue solution, allowing you to filter out the chalk residue, which is insoluble in water.
Chalk is Calcium Carbonate, aka CaCO3, so it's only one substance.
yes chalk is a textile and it can come in many colours but the mainly used colour of chalk is white.
i think it would be a suspension

You can change the color of chalk by mixing powdered pigments or food coloring with the chalk dust and a small amount of water to create a paste. Incorporate the paste into the chalk mold and allow it to dry completely before using.
