What happens when pure water and salt water mix?

Answer 1

Salt-water and fresh-water are not different immiscible substances. Salt water is simply water with dissolved ions in it, which, when compared relatively to a body of fresh water, is denser. However, taking fresh water and adding it to salt-water, or the other way around, simply dilutes the concentration of ions and makes the whole solution less dense. The ions will be evenly distributed throughout the new solution, barring temperature, pressure, and other differences. What can occur in the real-world large-scale of the oceans however, is that differential evaporation and precipitation rates, and other effects, can cause some level of stratification. Look up halocline, for example.

Answer 2

usually when salt and water are mixed salt gets dissolved in the water obviously after all it's soluble. and due to it the water gets salty and the proportion of potassium gets increased in the water.

Answer 3

Of course they do. Think about it. The Mississippi river empties into the saltwater Gulf of Mexico with the two water, fresh and salt, mixing just fine. Salt water is just water with much dissolved ions of certain types in it, nothing more.

Answer 4

When pure water and salt water mix, the salt in the salt water will begin to dissolve into the pure water. This process is called diffusion. Over time, the salt concentration in the mixed water will approach a uniform level throughout the solution.

Answer 5

The salt dissolves in the water, up to a certain point called saturation. Beyond this, any extra salt will simply sit on the water without any further dissolution.
