Is this correct, chemistry?

Salt (NaCl) is soluble in water because Water is a polar substance (not NaCl). This means the Oxygen is slightly negatively charged and the hydrogen positively charged. These charges attract the Na+ and Cl- respectively, meaning that the Salt becomes 'separated' and joins on some of the Water ions.
 
yes, the salt "dissociates" or "ionizes" into free swimming Na+ and Cl- ions that the water molecules had pulled from their originally solid crystalline structure. You explained the concept accurately.

you said "water ions".. the polar water molecules are not considered ions. Distilled water however does ionize at a small fraction, but the leads to the topic of Kw, the ionic product of [H3O+] and [OH-].
