• A homogeneous mixture of two or more substances which are chemically non-reacting, whose composition can be varied within certain limits, is called a solution.

                                          Solution = Solute + Solvent

• Solvent: A substance in which a solute gets dissolved is called a solvent.

• Solute: A substance which gets dissolved in a solvent is called a solute

A solution has a solvent and a solute its component of the solution that dissolves the other component in it (usually the component present in larger amount ) is called the solvent.

The component of the solution that dissolved in the solvent (usually present in lesser quantity ) is called the solute.

 Also, You asked that 2kg of salt dissolved 1 teaspoon of water, this is not possible 2kg of salt will never dissolve in 1 teaspoon of water.

In case, if solid is dissolved in a liquid to prepare a solution then the liquid will be solvent with large in amount as compared to the salt which is a solute with small quantity.
