- In the salt water solution , the solvent is water
- If the solvent of a solution evaporates , then the solute of the solution will remain
- So, if the water in the salt water solution evaporates, then the solute of the solution will remain

- If something is in the sunlight then that something will absorb solar energy
- Salt water is placed in sunlight for a day
- Therefore, the salt water will absorb solar energy

- The salt water will absorb solar energy
- In the salt water solution, the solvent is water
- Hence, the water in the salt water solution will absorb solar energy

- The water in the salt water solution will absorb solar energy
- If a substance absorbs solar energy then that substance will increase in temperature
- So, the water in the salt water solution will increase in temperature

- The water in the salt water solution will increase in temperature
- Temperature is a measure of heat energy
- So, the water in the salt water solution will increase in heat energy

- The water in the salt water solution will increase in heat energy
- Evaporation means a substance changes from a liquid into a gas by increasing heat energy
- Water is a kind of substance
- Therefore, the water in the salt water solution will evaporate

- If the water in the salt water solution evaporates, then the solute of the solution will remain
- The water in the salt water solution will evaporate
- Therefore, the solute of the salt water will remain after water evaporates

- The solute of the salt water will remain after water evaporates
- In the salt water solution , the solute is salt
- Therefore, the salt in the salt water will remain after the water evaporates

So, the salt in the salt water will remain after the water evaporates
