If you have ice tea and stir in some sugar which part is the solution?

The entire mixture of ice tea and sugar is the solution.

Here's why:

* Solution: A solution is a homogeneous mixture where one substance (the solute) is dissolved evenly into another (the solvent).

* Solute: The sugar is the solute because it dissolves into the ice tea.

* Solvent: The ice tea is the solvent because it dissolves the sugar.

So, when you stir sugar into ice tea, you're creating a solution where the sugar is evenly distributed throughout the ice tea.
