Water (pure) is NOT a solution, but it can be a solvent eg. of salt, sugar, vinegar, alcohol, soda, ammonia gas, hydrogen chloride gas (hydrochloric acid is formed) etc.
Solution
Water
evaporation or boiling!!!
CO2(aq) because a solution means the substance is dissolved in water.
An aqueous solution is a solution in which water is the solvent. Substances can dissolve in water to form an aqueous solution due to the polarity of water molecules. Common examples include salt dissolved in water and sugar dissolved in water.
hypertonic solution!
Hypotonic.
It is a solution.
Solution
Carbon dioxide is an inorganic gas; but carbon dioxide can exist as a water solution.
i believe you mean a saturated solution
Water
H2O is the chemical equation (not solution) for water. It means: 2 atoms of hydrogen, and 1 atom of oxygen.
of course kool-aid is a solution.it's a solution composed of two mains substances sugar and water.
evaporation or boiling!!!
strong acid
It will be an aqueous acetic acid solution. normally water is added in order to decrease the concentration of an acid & gives the diluted form of it.
