The HCl molecule is not purely covalant.It has approx. 40% ionic character and 60% covalant character . so the HCl is partially polar and in water it dissociates into H+ & Cl-.

When the polar substance Hydrochloric acid GAS is bubbled in water, the polar property and H-bonding ability of water is able to orient itself so that the more electronegative Cl in HCl forms hydrogen bonding with the Hydrogen part of water. Similarly, the electropositive H part of HCl forms hydrogen bonding with the Oxygen of water. These bondings are strong enough (energy-wise) to break the polar covalent bond of HCl forming the ionization of HCl.
Moreover and more important (thermodynamically) is the fact that once the HCL is ionized, the individual ions H+ and Cl- are very stable in solution, being stabilized by the solvating property of water. Formation of stable ions further enhances the reaction to go one way ..that is, the dissolution of HCl in water.

Basically, HCl has a covalent bond, it is a fairly weak bond. Water is able to break this bond

the bond between the H and Cl is easily broken, and it dissolves in water

HCl(g) is easily ionized in water beacue of its bonding. It is a weak covalent bond .

It can be dissolved, isonized..
Water is polarized.
