Rainwater typically contains very low levels of salts, with an average salinity of around 3.5 parts per thousand (ppt). This is lower than the salinity of ocean water, which is around 35 ppt. The salt content of rainwater can vary based on factors such as location, air pollution, and proximity to the coast.
No. Salt is too heavy to evaporate. Even though some rain water is evaporated from the ocean it does not contain salt. No. When the water evaporates, it leaves the salt behind.
Most rain cannot be considered freshwater. It usually if full of acids and pollutants from our horrible economy.
The rain water comes from water vapor that has gone into the atmosphere, mostly from oceans. 'Vapor' means molecules that are bouncing around in mostly empty space without spending much time in contact, unlike a liquid where they stick together. When the vapor cools enough, it condenses into liquid water that falls as rain. So why does the water vapor lack salt? Dissolved salt consists of ions- electrically charged versions of atoms. In liquid water, the electrically charged parts of the water molecules arrange so that on average their positive parts are near the negative ions, and the negative parts nearer the positive ions. That greatly lowers the energy of the ions, compared to the energy they would have off on their own. In other words, the ions stick to the liquid water. They actually stick to it much better than the water molecules do. So water molecules evaporate off into vapor, leaving the salt behind.
Heavy rainfall makes water less dense because an increase in salinity leads to an increase in density. Rain does not contain any salt. Therefore heavy rainfall makes ocean water less dense. =)
Salt water evaporates from the ocean's surface, leaving behind the salt. The water vapor rises into the atmosphere and eventually condenses to form clouds. When the clouds cool and the water droplets become too heavy to stay aloft, they fall as precipitation, which is freshwater rain since the salt is left behind during the evaporation process.

No, salt absorb moisture.
Rain is formed when water droplets in the clouds combine and become heavy enough to fall to the ground. The salt particles in the ocean water are left behind when the water evaporates to form clouds, so the rain that falls is typically fresh water. Salt water is not generally carried up into the atmosphere where clouds form.
Distilled water doesn't contain salt.
Rain water does contain salts but not those which are found in sea water. Rain contains salts which are usually obtained from atmospheric pollutants such as nitrates, sulphates, and so on.
Rain will better water plants because salt water has salt which will dehydrate the plant.
No sea salt water contain many salt but water with salt contain sodium chloride. But maybe for about 2-3 days.

Water that does not contain salt, and is not salt water.
Salt water contain dissolved sodium chloride.
Yes, the sea does contain salt water.
