a glass of lemonade
sofia loves making lemonade with fresh - squeezed lemon juice and water. she noticed that after a day or two in the fridge, her lemonade would turn brown and lose its fresh taste. while looking at the ingredient list on a store - bought lemonade bottle, she saw that it included sugar and citric acid. sofia wondered if adding these ingredients to her homemade lemonade would help preserve its color and freshness. to test this idea, sofia prepared six identical bottles of freshly squeezed lemon juice from the same batch. she added one teaspoon of sugar to two of the bottles and one teaspoon of powdered citric acid to the next two. she added nothing to the remaining bottles. then she labeled the bottles and placed them in the fridge. after three days, she observed that the bottles with plain lemon juice and the ones with sugar had all turned brown, while the ones with citric acid stayed bright and fresh. sofia now predicted that citric acid was more effective than sugar at preserving lemonades color and freshness.

Sofia now predicted that citric acid was more effective than sugar at preserving lemonade's color and freshness.
