What ionic compounds are in lemon juice?

Lemon juice is a complex mixture, but the primary ionic compounds present are:

* Citric acid (H₃C₆H₅O₇): This is a weak organic acid that contributes to the tart taste of lemons. While not an ionic compound itself, it can ionize in water, forming hydrogen ions (H+) and citrate ions (C₆H₅O₇³⁻).

* Potassium (K+): Potassium is a mineral found in lemon juice. It exists as the cation (K+) in solution.

* Calcium (Ca²+): Calcium is another mineral present in lemon juice. It exists as the cation (Ca²+) in solution.

* Magnesium (Mg²+): Magnesium is a mineral present in lemon juice and exists as the cation (Mg²+) in solution.

* Sodium (Na+): Sodium is a mineral found in lemon juice, existing as the cation (Na+) in solution.

In addition to these, trace amounts of other minerals like iron (Fe²⁺) and zinc (Zn²⁺) may also be present.

It's important to note that these ions are not present in lemon juice in their pure ionic form. They are present as part of the dissolved molecules of the various compounds within the juice.
