Salt Water
When salt is added to water, it dissolves and forms a solution. This process is called dissolution. The addition of salt lowers the freezing point of water and raises its boiling point. However, the addition of salt does not change the density of water.
The salt in the cup will dissolve but the water is still very much salty.
The salt will dissolve in the water to create a salt solution. At 30 degrees Celsius, the solubility of salt in water is high, so it should fully dissolve. The resulting solution will have a higher density than pure water due to the dissolved salt.
It's not possible to spectate salt and water since their interactions happen at the molecular level and cannot be visually observed. You can, however, observe the effects of salt dissolving in water, such as changes in clarity or taste.
If you let a candy soak in salt water overnight, the candy will absorb the salt water causing it to become softer and potentially change its taste. The salt may also dissolve into the candy, altering its flavor profile.
It would die and so would a salt water fish in fresh water.
You get salt water.
the salt dissolves and the water will become salt water
You will have some salt and some fresh water.
the salt will disolve
When you place a raisin in salt water, the water around the raisin becomes more concentrated with salt due to osmosis. This causes the water inside the raisin to move out towards the salt water, resulting in the raisin shrinking and becoming wrinkled as it loses water.
It would die - Fresh water fish are poisoned by the salt levels
it becomes salt water
they will die
When left in a warm place, water would evaporate due to increased temperature, leaving behind salt crystals. Salt does not evaporate like water, so it would remain in its solid state even in a warm environment.
salt will dissolve
The salt would dissolve, which you can reverse by boiling the water.
