What is in lemon juice that makes it an acid?

Answer 1

Lemon juice is acidic primarily due to its high concentration of citric acid, which typically accounts for about 5-8% of its composition. Citric acid donates hydrogen ions (H+) when dissolved in water, resulting in a decrease in pH and contributing to its sour taste. This acidic property is what makes lemon juice effective in cooking, preserving foods, and even as a natural cleaning agent.
