Sodium Hydroxide, Hydrochloric acid, Sodium Citrate, Citric Acid.
- Citric acid is a weak acid that’s widely found in nature. For example, citrus fruits contain about 5-8% citric acid. Sodium Citrate is a derivative of Citric Acid.
- We add sodium hydroxide and hydrochloric acid to get the pH balance right, but they aren’t actually in the final product. This is because they transform into salt and water when combined.
