The water molecules move around the salt ions
In water, the salt separates into positive and negative ions.
The water molecules move around the salt ions.
Water is the solvent because it is what dissolves the solid salt into the solution. The water molecules pull apart the crystal structure of salt and surround the salt ions.
Polar molecules like sugar and ionic substances like salt will dissolve in water.
salt is composed of Atoms. not Molecules. i know i am answering my own question but i found the answer.
Saltwater is a mixture of solid and liquid molecules. Once the salt dissolves, the substance becomes a solution.
Salt dissolves faster in heated water. Sugar dissolves faster in regular water.
Salt dissoves better in water as the molecules which go to make up the salt become invisable to our eyes as they disperse in the water. Wheareas the molecules in baking soda remain visible as seen by the milkiness of the water.
Salt dissolves faster in heated water. Sugar dissolves faster in regular water.
The salt is the solute and the water is the solvent. Water is the solvent because it is what dissolves the solid salt into the solution. The water molecules pull apart the crystal structure of salt and surround the salt ions.

Water "dissolves" salt. Water does not absorb salt.
Students will make a 2-D model of a salt crystal and use water molecule cut-outs to show how water dissolves salt. After seeing an animation of water dissolving.
