Objective When something dissolves an additional substance (the sol vent) is needed. Water can just take so much salt. Dissolving salt in water may be written as a chemical reaction, where sodium chloride dissociates into Na+ ions and Cl- ions in water. They will relate their observations to the structure of salt, water, and alcohol on the molecular level. Thus, any ionic compound that is soluble in water would experience a chemical change. Why is dissolving salt in water an endothermic process ... Along the way, you'll get a side dish of acid-base chemistry just to round out the "flavor" of the salt-water experience! The polarity of water comes from the differences in electronegativity in . It is contrary to the notion of "pressure . If the salt does not immediately dissolve, try mixing it with a spoon or spatula. Studies show that people who soak in hot baths containing Epsom salts experience pain relief from arthritis, muscle spasms, and other . Sugar can dissolve easier than salt because when you add 8 spoons of salt into water the salt already starts to stay in the bottom of the cup. The molecular structures of salts is arrayed in a specific pattern when in solid form. In contrast, dissolving a covalent compound like sugar does not result in a chemical reaction. Pour the salt into the water. And, when you add 30 spoons into water the sugar just starts to stay in the bottom of the cup. This process continues until the salt is completely dissolved.
