Salinity

Imagine trying to dissolve sugar into your morning coffee but realizing there’s just too much sugar for the amount of liquid in your cup. This is similar to the concept of salinity, where the focus is on how much salt is dissolved in a given amount of water. Just as the coffee can only hold a certain amount of sugar before it becomes oversaturated and leaves sugar undissolved, water can only dissolve a specific amount of salt before it reaches its salinity limit, highlighting the balance between the amount of solute (sugar or salt) and the solvent (coffee or water).
