Why does salt dissolve in water?

Table salt is not made of isolated NaCl molecules in the solid; it forms an extended ionic lattice.

Mis tegelikult toimub?

Teadus jääb meelde, kui definitsioon seotakse millegi mõõdetava või vaadeldavaga.

Na loses one electron to form Na+; Cl gains one to form Cl−, while their proton counts stay unchanged.

Kasulik mõttepilt

Table salt separates into ions in water because polar water molecules can stabilize charged particles. The crystal does not simply 'vanish': its ions become dispersed through the liquid.
