When hydrochloric acid (HCl) is added to water, it dissociates into its constituent ions, hydrogen ions (H+) and chloride ions (Cl-), as represented by the equation:

HCl → H+ + Cl-

The hydrogen ions will react with the hydroxide ions (OH-) produced by the magnesium hydroxide (Mg(OH)2), as represented by the equation:

H+ + OH- → H2O

This reaction produces water (H2O) and leaves excess hydrogen ions that make the solution acidic. Therefore, the resulting solution will be basic.
