Because Marble chips, Calcium carbonate, (CaCO3), require an acidic pH (less than 7) in order to dissolve at a useful rate*. The lower the pH, the faster it reacts. At a pH of ~8 or higher, it loses almost all of its aqueous solubility.
* Actually marble chips are slightly soluble in water. This is why they make such great stalactites and stalagmites. However, for most practical purposes, they are insoluble in water because they dissolve at a very slow rate, slow enough to be impractical for almost any useful purpose.

Decomposition occurs at various stages and many products and byproducts are formed, depending upon the pressure, temperature, and pH, all of which tend to vary at given stages of reaction. It decomposes, more than dissolves. Products can include:
CaO,
Ca(HCO3)2,
H2CO3,
Ca(OH)2,
Ca+2,
CO3-2,
HCO3-,
H+,
CO3-2
CO2
H2O,
OH-,
Boiling chips are not soluble in water.
pH is measured only in solutions or liquids. Marble chips has not a pH.
it depends on amounts of marble and concentration of acid
Marble chips are calcium carbonate. If the hydrochloric acid is strong(concentrated), it acts upon the marble and corrodes it liberating
No, you cannot grind marble chips using a pestle and mortar. This tool is typically used for more kitchen applications then home repair.
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.

No the water would drain around the chips. They would not absorb water.

It is in most inorganic acids.
Complete ionization in water. Very fast reaction with marble chips/powder.

Calcium Carbonate
Hydrochloric acid, HCl, and marble chips, CaCO3 is a chemical reaction that produces calcium chloride, CaCl2, carbon dioxide, CO2, and water, H2O.CaCO3(s) + 2 HCl(aq) --> CaCl2(aq) + CO2(g) + H2O(l)
