Liquid water in the earth's air is an example of a solution. what type of solution would this be?
murzikaleks [220]
Solutions are homogeneous mixtures made up of two non-reacting compounds. The component which is present in large quantity is called as solvent and the component in small quantity is called as solute There are six types of solutions.
                                       
1. Gas (solvent) - Gas (solute) Example= Air

2. Liquid (solvent) - Gas (solute) Example= Fizzy Drinks

3. Liquid (solvent) - Liquid (solute) Example= 96% Ethanol in Water

4. Liquid (solvent) - Solid (solute) Example= Sugar in Tea

5. Solid (solvent) - Solid (solute) Example= Brass, 18 caret Gold

6. Solid (solvent) - Gas (solute) Example= Marshmellow

Result:
          In equation earth air is solvent (as it is in large quantity) and water vapors (gas) which are in small quantity is solute.
So, it is Gas - Gas Solution.
