Salt
In chemistry, a salt is any neutral chemical compound made of cations (positive ions) attached to anions (negative ions). The main kind of salt is sodium chloride with the chemical formula NaCl. It is formed when hydrochloric acid is added to sodium hydroxide. The reaction is as follows HCl+NaOH2 gives NaCl+H20+heat
Mixtures of salts in water are called electrolytes. Electricity is able to pass through electrolytes, as well as molten salts.
Salts can melt ice, because salts lower the temperature needed for liquid to freeze.[1] Because of that, streets are sometimes treated with salt in winter, if the temperature is only a little below freezing.[2]
A salt can also be explained as an ionic compound which dissociates, forming a positive ion other than hydrogen ion, and a negative ion other than hydroxyl ion.
