How does water dissolve salt quizlet
WebSep 2, 2024 · Salt water is salt mixed with fresh water. However, salt in cold water does not dissolve as well as if the water is warm. Warm water has more room between the water molecules, allowing more salt to fit. Cool water molecules are tighter together and will not allow much salt to dissolve. WebWater molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution. Find out more Adhesion/cohesion
