it is a suspension because; suspension = a solid and a liquid mixing which is what chalk dust and water is. :)
No. Chalk is mostly calcium carbonate, CaCO3, which is insoluble in water. The chalk will be visible at the bottom of the mixture, which means the concentration is not homogenous throughout, which it must be in order to be considered a solution.
Yes, chalk and water would form a suspension.
Nope But I Can't Answer Why Sorry! =P
yes chalk will dissolve into water and form an aqueous solution

It is a mixture, not a solution because the solubility of calcium carbonate in water is extremely low.

Yes, it is true.
Yes, it is true.
It is a nonhomogeneous mixture.
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.
yes chalk is denser then 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.
First you mix both chalk and salt in water. From the solution that you get, you can filter the chalk out because it is non soluble in water. As for the salt, all there is to do is to just evaporate the water out.
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.
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.
No it is not. Limestone itself is not a solution. Limestone is a rock which is primarily calcium carbonate as are marble and chalk. Calcium carbonate will react with water if the water contains dissolved Carbon Dioxide (forming a mild carbonic acid) resulting in Calcium Bicarbonate which is soluble and does form solution in water.
due to capillary action water raises in chalk.. and the air in it comes out in form of bubbles...
yes,it is a suspension because it is a heterogeneous mixture which is given in the question so it can not be a true solution. in the case of suspension the chalk powder in water is insoluble and the particle size is more than 2000 but in colloidal solution both in dispersed phase and dispersed medium the particles are soluble. so, it is a suspension.generally chalk powder in water is insoluble
Due to the chemical composition of Chalk, you can separate it from water either by filtration of evaporation.
Filter. The copper sulphate will pass through the filter paper. The undissolved chalk will remain in the filter paper.
hey hey when the chalk gets put into water the water goes cloudy and eventually sinks to the bottom. from Sunnibunny, ginkelbunny
Chalk is calcium carbonate, which is insoluble in water. Hence, it can easily be removed by filteration. Moreover, calcium carbonate has reverse solubility in water, i.e. its solubility reduces with increase in temperature. Thus, the solution may be heated and then filtered.

most ionic compounds will dissolve in water to form ions in solution.
Chalk is a form of calcium carbonate, so chalk dust is also a form of calcium carbonate.
