Why Does Sodium Chloride Dissolve In Water?

A. Yes, sodium chloride can dissolve in water. This is because sodium chloride has alternating sodium cations and chloride anions. Water is a polar molecule meaning that it has an uneven charge distribution. The negative charges (oxygen) of water attract the positive sodium ions available in the sodium chloride. The same theory works for the positive ions (hydrogen) in water that attract to the chloride ions in sodium chloride. The negative and positive attracts allow the sodium chloride to dissolve in water. 

Water is a polar liquid and NaCl (common table salt) is also a polar compound, therefore as both water and NaCl are polar water will break the bonds of NaCl and NaCl will go into solution.

Water is a polar molecule. NaCl is an ionic compound that has full ionic charges. In chemistry solutions "like dissolves like", therefore the polar attributes of both the NaCl compounds and the water molecule are the reason table salt dissolves in water.

When ionic substances such as NaCl is placed in water, the water molecules interact with the ions on the surface of NaCl. Sodium chloride is soluble, that means the attractive interactions NaCl has with the water molecules over comes the ionic attractions within the lattice of NaCl. The solvated ions move off the surface an become separated in solution, giving the solution a clear apperance. :)

The slightly negative oxygen in the water will be attracted to the negative Na+. When the oxygens surround the Na+ energy will be released. The slightly positive hydrogens will surround the chloride, and more energy will be released. Therefore it dissolves as this is the energetically profitable thing to do.

We all know like dissolves like.water and sodium chloride both are inorganic compound so they dissolve each other.

Salt dissolves in water because of the hot energy. When the water is hot the energy increases and the water molecules moves faster than when the water is freezing. Because of all the water molecules moving those molecules could break the salt molecules making the salt to dissolve
