Is lemonade a mixture or pure substance?

* Mixture: A combination of two or more substances where each substance retains its own properties.

* Pure substance: A substance that has a fixed chemical composition and cannot be separated by physical means.

Lemonade is made by combining water, lemon juice, and sugar. These ingredients retain their individual properties:

* Water: Remains water, a pure substance.

* Lemon juice: Contains citric acid and other compounds from the lemon.

* Sugar: Remains sugar, a pure substance.

Since you can separate the ingredients of lemonade through physical means (like evaporation to remove water or filtration to separate the solids), it's a mixture.
