solution
Pure water is the standard for a neutral fluid (neither acidic or basic.) Ammonia is a basic solution.
Water is pure, not a solution.
Ammonia in its pure state is a single molecule (NH3) which, depending on pressure, can be either a liquid or a gas. Household ammonia (aqua ammonia) is a solution of ammonia in water which is usually described as NH4OH or as its componest ions NH4+ and OH- If you had pure ammonia in a container (as a liquid) it would rapidly change to ammonia gas. An ammonia solution (household ammonia) is much more stable.
No. Pure water is a compound, which is a pure substance. A saltwater solution is a mixture of water and salt, and is not a pure substance.
Yes, pure water can be classified as a solution because it is a homogeneous mixture of water molecules.
Ammonia is a compound and so can exist as a pure substance. Household ammonia is not pure. It is a 3% ammonia solution. The other 97% is water. Pure ammonia is very dangerous.

Pure sugar is a compound, which is a pure substance. If you dissolve sugar in water, you will have a homogeneous mixture, which is a solution.
Adding pure water to an acidic solution will dilute the solution, causing the pH to increase. This is because the concentration of H+ ions, which determine the acidity of the solution, decreases as more water is added.
By evaporating the water of the solution and condensing it.
