You are making a glass of Kool-Aid. You put 2 tablespoons of sugar, stir it until all the sugar is dissolved and then taste it. You realize it is not sweet enough so you add 10 more tablespoons of sugar and stir it. You notice that there are still solids in the glass. Do these solids indicate that a chemical reaction occurred?

Yes because you saw solids form and the color change, which indicates a chemical reaction.

No because the solids are not a new substance.

Yes because the solids are a new substance that formed between the Kool-Aid and water.

No because a chemical reaction has to show a change in denisty.
