When pure water and sodium chloride combine what do they create?

When pure water and sodium chloride (table salt) combine, they create a saline solution. The sodium chloride dissociates into sodium ions (Na⁺) and chloride ions (Cl⁻) in the water, resulting in a solution that conducts electricity and has a salty taste. This process is a physical change, as no new substances are formed, and the properties of the individual components are retained within the solution.
