The answer is "yes": Rainwater does contain dissolved solids. A few things have to be known to understand how rains form.
1. There are many kinds of substances floating in the air in the form of tiny particles, e.g. dust, pollen grains.
2. The density of water vapor is lower than that of the air, therefore water vapor goes up in the air.
3. The higher the altitude, the colder it becomes.
Water vapor cools down as it ascends in the air. The molecules of the cooled water vapor are attracted to the surface of the floating solid particles. It takes billions of water molecules to form a droplet. The droplets collide with each other and merge into bigger and heavier water drops. It takes about a million droplets to make a raindrop, which finally becomes so heavy that the air cannot hold it up any longer. Then many such drops fall out of the sky, and that's how the rain forms.
The tiny solid particles floating in the air are very important--they are the bases of rain drops. In fact, without solid particles, there will be no rains no matter how much water vapor there is in the air.
Artificial rainmaking is to spray very fine solid particles in the air so that water vapor can have bases to form water drops.
Therefore, rainwater is not pure water, and there are many tiny solid particles within every raindrop. Some solid particles may dissolve in water, some not.

How would you show that sea water contains more dissolved solid than rainwater does?
it contains dissolved water 'salt'
When water evporates does the dissolved solids in the water also evaporate?
The dissolved solids are not evaporated.
What happpens to the boiling point of a solution?
At the boiling point liquids become gases and if the solution contain dissolved solids they remain as residues.
Does rainwater contain uric acid?
No
The removal of dissolved solids from seawater?
Desalination.
How would you show that sea water contains more dissolved solid than rainwater does?
it contains dissolved water 'salt'
How can you check purified water does not contain dissolved solids?
You can check by evaporating the liquid if something remains then the water is not pure.
When water evporates does the dissolved solids in the water also evaporate?
The dissolved solids are not evaporated.
How do freshwater and saltwater compare in terms of their dissolved solids?
The amount of dissolved solids is less in freshwater.
Carbon dioxide forms a weak acid called carbonic acid when dissolved in water How can this be a significant factor in the formation of acid rain?
Carbon dioxide in the atmosphere is dissolved in water, making natural rainwater slightly acidic, so when other gases such as sulphur dioxide are dissolved in rainwater, it becomes more acidic than it would be if it didn't contain carbonic acid.
What are the solutions of solids dissolved in solids called?
Alloys.
What happpens to the boiling point of a solution?
At the boiling point liquids become gases and if the solution contain dissolved solids they remain as residues.
What is a totally dissolved solid?
it has to do with how many dissolved solids are in water
What is the difference between total dissolved solids and total suspended solids?
total dissolved solids is how much of the solid is dissolved in the liquid, while suspended total suspended solids is the amount of the solid floating in the liquid. e.g. if you had a solution with both and you filtered the solution then evaporated out the liquid, the solids that you filtered out would be the suspended solids, and the the solids remaining after evaporating the liquid out would be the disolved solids.
What is the solids that dissolved in the solvent?
The solute
Does rainwater contain uric acid?
No
Does the level of total dissolved solids in water affect chlorine disinfection?
The level of total dissolved solids in water does affect chlorine disinfection. That's why there is a recommended specification for the level of total dissolved solids in water for the water that is sent to homes.
