Answer:
No, though the sawdust is capable of absorbing quite a lot of water and will soften as a result, but its cellulose structure will never actually dissolve into the water like salt, sugar, and other substances do.
In water the solubility of chalk is low so, only a minute amount of calcium carbonate can be dissolved in the water and rest will be remain solid. Chalk is normally made of mineral so, usually it does not dissolve in water.Jul 19, 2016
