The discussion revolves around the chemical composition and pH of citric acid, particularly in the context of lemon juice. Participants explore the relationship between citric acid and its presence in lemon juice, addressing misconceptions and seeking specific pH values.
Participants express differing views on the characterization of lemon juice and the concept of pH related to acids. There is no consensus on a definitive pH value for lemon juice, as it is acknowledged that it can vary.
Participants discuss the importance of concentration in determining pH and the implications of defining substances as "pure" versus solutions. The discussion reflects varying assumptions about the nature of citric acid in different contexts.

rainbow-chick said:what i was really looking for was the pH of lemon juice i read somewhere that lemon juice was pure citric acid...?? sounds stupid now that i think about. sorry and thank you for your help!
symbolipoint said:"Pure citric acid" ---- nonsense since citric acid itself is a solid. Lemon juice is a liquid, a solution which contains a few solutes including citric acid. (Condition assumed, room temperature. ) Good thinking on your next thought shown from your message.
