Why does the level of water not change when common salt is dissolved in wster

Answer» Because particles have space between them
Common salt dissolves in water i.e. its atoms occupy the spaces in the water molecules.Salt (sodium chloride) is made from positive sodium ions bonded to negative chloride ions.Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions.
