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.
If you put a piece of chalk in water, don't expect much to happen. The chalk, which is calcium carbonate (CaCO3), will displace some water and sink. It will grow in mass by a small amount since it is permeable and is absorbing the water.
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.
yes chalk is denser then water.
In order to dissolve chalk in water, vinegar needs to be added. The vinegar has acid in it that eats away at the chalk to dissolve it.
It get hotter and if it is frozen it melts. If it is melted it boils.
No. Chalk is insoluble in water. Adding sugar will not change that.
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.
When you breath chalk when you have your allergies you start to cough and your eyes get filled with water ( watery).
To fix a mixture of 1 part water to 3 parts chalk, you could add more chalk to thicken the mixture and balance out the excess water. Gradually add small amounts of chalk while stirring until you reach the desired consistency. Alternatively, you could increase the overall quantity of the mixture by adding more chalk and water in the appropriate ratio to achieve the desired result.

Water is the solvent and chalk is the solute.
When you mix chalk with water and then evaporate the water, you are left with chalk dust or solid chalk residue. Evaporating the water removes the liquid component, leaving behind the solid chalk particles that were initially dissolved in the water.
To make chalk paint waterproof, you can add a water-based polyurethane sealer or wax to the painted surface. Apply multiple coats for better protection against water damage.

No chalk is not solouble. When chalk is put in water the water becomes a suspension ie the particles of chalk keep floating in water.
