water is a polar covalent solvent. because of this polar nature, the electron pair forming the covalent bond between H & O in water is shifted more towards the comparatively more electronegative atom ie O, so in water O atom acquires a partial -ve charge, & H atom acquires a partial +ve charge, the NaCl crystal can be regarded as an aggregation of Na+Cl- units. so, when it is dissolved in water the Na+ ions are attracted towards the oppositely charged O atoms of H2O, similarly the Cl- atoms are attracted towards the +vely charged H atoms, also the force existing in a crystal of NaCl, between Na+ & Cl- species is electrostatic force of attraction, water has dielectric const 80 times than that of air, so the force of attraction in water between Na+ & Cl- diminishes to 1/80 th its previous value(Coulomb's law), as a result of these forces, the molecules in crystal splits off & the ions goes into the soln.
In case of NaCl, Lattice energy< Hydration energy ; so its soluble in water.

When NaCl dissolves in water it dissociates and becomes Na+ and Cl- ions. They are able to get between the H2O molecules so volume is not conserved. In a solution the solute is evenly mixed all the way through. Where ever you take a sample it will be the same concentration of salt water.

a miraculous thing happens, when sodium choride is dissolved in water, a genie pops out of the colossal reaction and grants you 3 wishes.. after the three wishes are granted the reaction energy drops vastly and the solution becomes an aqueous solution of Na+ ions and Cl- ions... be careful though, this genie is tricky.. make your wishes quickly or else...

Na+, Cl-, and H2O become evenly distributed in the solution.

I do recall that it speeds up the melting process of ice. And that it is also gives us our wonderful salty oceans.
To answer the question, it gives you salt water.

They form ions, with Na becoming a cation and Cl becoming an anion.
NaCl ----> Na+ + Cl-

you get a salt solution, or brine
